I've just purchased the game from China's PSN Store since it's much cheaper. The Japanese version would've required me to drop like $75 on PSN cards whereas the Chinese version was only about $46 and you could purchase it quickly and conveniently with PayPal. Plus, you get a free bonus theme this week. I've been refreshing both China and Japan's Stores the entire day until the game finally showed up, lol. I thought Yuki and Len would be available on release day but then I realized the DLC's release date(s) hasn't been announced yet. But they'll be free the first week which is awesome.
Also, thanks for the change list posted above. I've been looking for that. It says Asuna's dash has been increased and her Standing A + B (Shooting Star) has longer reach now. But I also noticed that her QCF + A + B (Parallel Special) can no longer off-the-ground no matter what; that's something that wasn't noted. Not that you'd want to do that anyway.
