One thing to discuss is the big time gap for each region. Europe getting it last is a slap in the face to many Europeans who finally didn't have to wait so long for their pokemon release date, and now they aren't getting it until after Christmas..
While, as a brit, the delayed release date is disappointing, I think that it's even worse than it may first seem.
I believe that already there is ample evidence to conclude that this game is going to be rushed. The fact that it was only just announced now at the end of May while being scheduled to release this Autumn in Japan is already worrying as it gives less time for hype to build, though when in Autumn matters greatly. I'm guessing this will be released near the end of autumn considering the winter release date for America. Even though IIRC correctly ORAS had a similar schedule, the game was developed greatly at that point and we had trailers and the like soon thereafter. We only have a logo and a rather odd name for this game. Does this mean that the game isn't in late enough stages for a trailer to be compiled? Possibly.
Furthermore, the randomly delayed release dates also implies a rushed development. In recent times, copies of games are sent to shops ready to be bought before the release date so that games can have a near worldwide release. The fact that this game has such a broad time gap between releases makes me think it's going to be more of a rush to get units onto shelves, which would be hypothetically unnecessary if the development is well planned.
Neither of these are huge indications on their own, but combined this title already has me a little nervous.
BTW, WTF is that name? This reminds me of Super Mario 3D Land and the whole "stick the ending in the middle of the name, it's cool! :o
Edit: Actually, I just had a thought. The randomly blank announcement this close to E3 COULD mean that we're gonna be treated to a show there with playable demos etc.. After all, we don't actually know that this will be handheld. I'll be honest, I sorta assumed that it would be, but it could just as easily be for the Wii U.
Which is good, because then Pokemon fans will have more of an incentive to buy the Wii U than Pokemon Rumble U, which was a huge disappointment. The Wii U needs to do well GDI!
