The international branch has an opportunity due to the BW10 set being reprint set to synch up the Japanese and International card games. This would be huge for the game and opens up all kinds of possibilities for international play. It would remove hype from the secondary market.
If they release it before worlds but after Nats then worlds would be an untested format for everyone except Japan, however that would be the last time that is true.
There is also the off chance TPCi, even if they do this, won't follow Japans rotation schedule, instead opting for an arbitrary date after worlds with a forced rotation that the game isn't designed for. This would partially defeat the purpose of a simultaneous XY1 release.
Just my thoughts. Should BW9 be released before worlds?
