All I have to say is that I think everyone will be surprised come October when it comes to the anime....
I've said this for the past couple of years ever since Platinum came out. The international releases were getting earlier and eariler, but yet everyone would always shut me down when I kept speaking of a 'worldwide release'. "Oh the translations and marketing will take up all the time". And look at where we are now.
Clearly the TPCi and The Pokemon Company of Japan have changed the way in which they communicate and share information so that Pokemon fans can truly experience it together.
So why not the anime? Just like with the games, maybe there's a special animators team that works on the original and dub together.
This user is a source of information regarding TPCi. These user predicted since Platinum that sooner or latter it would be a worldwide game release (even when many of us thought that it could be impossible). What happened now? That we have a worldwide release.
This user probably is a familar/parent/friend of someone that works on TPCi. This person probably don't klnow details about what will happen (and if they do, it won't be spoilered to you) but he/she knows "something" that gives her "opinion".
What this user is taking around is thatr this scenario could happen in the near future:
-Until October, Decolora Adventure.
-12th October, Alexa's debut.
-19th/16th October: Departure episode/Ash's flying in Kalos.
The week after that: Start Kalos.
I think that this users could be potentially right. We "forgot" something important here: You notice that the sho'ms amin purpose is promoting the games. We know that the dub episodes before they air in Japan (which means that they aren't dubbing earlier because CN).
There are two main date for buying the games: Release date and Christmas. And the anime is a event to promote selling the games, aprticularly because watching the anime could makethat many children will want that Santa Claus give the games to the children next Christmas.
If we are through a standard thing, the XY series will start on January 2014. Meaning that all the promotion would get lost by when the anime arrives.
In many places this can't be possible because it's very difficult to control so many schedules at the same time. In Spain, they won't do anything similar because they have already problems dubbing one season through the year and because they expect selling 200,000 copies and is a country that doesn't get profit right now. In the US they expect to get 3 millions of copies and they could get more profit fromt he franchise by airing the anime.
If I were a part of dubbing team, I will do this:
-If the anime has not aired Episode N, here of course; first we have to air Episode N (and the league if that's still pendent).
And if Episode N has aired and the games are released:
-Air the first episode.
Air the Alexa debut.
Air the departures and Ash's going into Kalos.
-Start XY.
In Canada, they pre-empted BF to air Diamond and Pearl; in many European countries they more than oprobably air BW teaser before Sinnoih ended for them. If TPCi wants, CN will air XY episodes and not the rest of Decolora because TPCI will want to promote XY.
The reason of why Da! don't have any plot whatsover is because the animators are aware of the worldwide release of the games. For if the dub wants to skip Da! they will accept by only airing the Alexa and departure episodes.
I don't think that the US will skip Da! and that he anime won'0t air in October.
But given the contents of what we know, for me I think that Best Wishes we have only the epsiodes that we know fromt he Data Broadcast and I think that the last episode will be Iris and Cilan specials (Zekrom being Iris).
That way the 93 days gap will be a 49 episode gap (19 episodes) which means the dub will start in ealry December just in time for Christmas.
