Well japanese 3rd parties are already leaving PS3/360 already. The only 3rd parties that still developing for PS3/360 are western developers anyway. Even CAPCOM I think that their last games thats on HD consoles are SF4 and Resident Evil 5 and other games that they announced during their gamer's day. I doubt they'll develop any games for HD consoles anymore, just look at preview sales charts in Japan, a niche title is competing with DBZ Burst Limit.
end of core gaming days prediction:
E3 2006-The beginning of the end. Wii introduced
E3 2008- Armageddon. Wii motion plus introduced. Wii Music. Reggie says Animal crossing was a core game. Massive disappointment. many Wii core gamers selling their Wii.
E3 2010- Tape runs out
