Turns out we got more in the volumes just like I predicted.
Be sure to check Coronis' volume 37 thread. (which is still on DP) For one it added more stuff than what was in the magazines plot to make everything make more sense and to make everything a lot more exciting. Oh, and it one of the biggest things you and every Special fan in the entire world could hope for -- IT INCLUDED SIRD REAPPEARING IN A TEAM GALATIC UNIFORM IN FRONT OF JUPITER. So yeah, pretty exciting. ^^ I knew she would appear again eventually (never expected DP though xD, although it fits perfectly and makes a lot of sense) and they would explain more about her. I also knew most if not all of the plot holes would probably be filled in the volumes. That's why I say it's best to never say squat about a Special arc 'til you get the volumes. xD Do you see why now?
At this rate we may actually get some other things in latter arcs like the Elite Four might appear near the end of DP, or at least by Platinum, and we might even get a Kanto Dexholder reappearance in HGSS, and a longer HGSS plot and one that makes more sense too. So yeah -- like I've said before just wait 'til the volumes for everything. ;P
Oh, and I hope this doesn't sound rude or know-it-all-ish, because I swear I don't mean it like that. I don't even mean it to pick at you or anything, I just wanted to tell you the good news and not to lose all hope for Special yet. ^^
