Here is what i hope for, now brace yourself cause its epic, also its very long so i apologize but i think its good :
Ash and company finish the unnova region in regular fashion, ash proceeds to unnova league he doesnt come out on top (1st) but in top 4 or 5 like in sinnoh.
After the unnova league Ash learns of a "Grand Region Battle Championship" that happens every so many years. The finalists (top 4 or 5) from every most recent league challenge/tournament, this includes ash and the other finalists from the unnova league, as well as the champion trainers from every region (champion trainers= strongest trainers from every region, also these trainers have participated in the "Grand Region Battle Championship" before or were nominated by someone who has been before to take their place) these trainers include all E4 members from every region and the champions from every region (Cynthia, Flint, Lance, Bruno, Karen, Steven, Drake, and the E4 and champ from B/W, etc). In addition to the recent finalists from the leagues, and champion trainers, all gym leaders from every region are all invited. This way Misty, Brock (and Forrest), Norman, Iris, Dento, Lt. Surge, all of em etc, are all there.
All the kanto/emerald battle frontier are participating becuase their all champion trainers having participated in the last grand region battle championships. This brings in all champs, E4, Gym leaders, Battle Frontier Heads, and Recent league finalists, thats a whole lot of cameos in one place, some just standins some battle. BUt May and Max are there too because their dad is in it. Dawn is there because She heard Ash was gonna be in it. Ash's Mom is there cause he is in it. All the professors from every region are there to witness the best of the best. Tracey is there he came with oak or somebody.
Gary is there cause he won the latest Kanto League same time Ash was in Unnova league, Tobias is there cause he won the latest Hoen League again same time, Ritchie is there cause he too participated in latest Hoen league.
Now that we've established what the tournament is and who will be there.
The writers could do one of two different things: #1 If there are Hoenn Remakes for Games then the Grand Tournament can take place in Hoenn (it switches regions every time) and Ash when going gets there like A month or so early so he travels some of Hoenn training to get ready. this is how we can go back and revisit the Hoenn region like we did Kanto, and Johto. OR #2 there are no Hoenn remakes and the grand tournament takes place on a huge island equally distant from all regions and this island houses the festivities every time theres a competition and it has a huge arena and housing facilities etc because its only use is every so many years when there is a grand tournament.
So yeah, let the festivities begin, we see all the old school and new school people we've all been dying to see cameo and its all awesome.
and o yeah.... as if there could be any other ending....Ash wins! shortly after winning and being recognized as a pokemon master a mysterious trainer who did not participate in the tournament challenges ash once everything settles down, (u know like kinda privately where theres only ash's close friends not in front of everyone) this new trainer beats ash with a pokemon he has never seen before. It turns out that this mysterious guy is the champ of the Generation 6 league and he uses his signature pokemon (u know how like cynthia has garchomp, well he has a signature one too). After beating Ash he tells him how he is good but he still has much too learn becuase (ANNOUNCER VOICE): the wide world of POkemon is always growing as new discoveries and friendships are made. this champ then invites ash to go to his region and explore/train then challenge him again in the region's own league. Ash says good bye to everyone and sets off into the 6th gen.
alternatively, ash could have gotten a ticket to the 6th region as a prize for winning the tournament. also the final match of the tournament could have been ash vs his father (they would introduce him) after defeating his father his dad goes back with his mom to pallet. or... (im sorry im almost done guys) ash's father could be the guy from the gen 6 region to challenge ash and thats where he has been trainin this whole time.
well that idea or one similiar to it with a huge tournament of epic proportions that includes all the old awesome characters we all love would be my favorite kind of cameo special a way to tie in all the previous characters and set the series in new directions.
I apologize for the length i do, but after reading this thread and some cool ideas i really wanted to express what i believe would be the all time coolest thing for the anime. Let me know if you like it and agree at all and or if you didnt like it i apologize for the length and waisting so much space in the thread.
This seems like more of a movie idea than one that would happen on the show. Like a straight to Cartoon-Network movie.
I like that a lot of the past characters would return. The Elite Four for each region and the Gym Leaders (aside from Misty and Brock) should mainly just be in quick background shots, though.
Maybe they would "host" the tournament and only really be seen lined up, side-by-side in a long camera shot.
Then the top 5 or so, like you said, from each region will compete in the tournament.
I don't think Ash should win though. If Ash wins, the anime should end. And why wouldn't the mysterious person who challenges Ash be in the tournament? Or for that matter, why would no other Gym Leaders from unvisited regions be in the tournament? Why just the ones that Ash has visited?
This idea would be fine for a anime-ending movie or finale. But I don't think that will happen for a long, long time.
