Well i heard that there's an speculating rumor that the xbox live subscription that we xbox owners pay goes to the development of xbox 360 games for exclusivity issues.
I've also read that when microsoft receives a xbox 360 exclusive title, the game remains exclusive only for their console in at least a year.
Regarding the prices of xbox 360s, All got a cut when the slim was announced so it's more cheaper. (150$ or something)
Though, NBGI is supposed to be collaborating with Project Diva. I don't know if that'll go into iM@S2, or if iM@S will just go into Project Diva (the last SP catalog's contents have already been shown/leaked and it consisted of no Vocaloid content XD).
NBGI hates Sega and Sega hates NBGI.
CURSE YOU MAN WHO INVENTED THE WHOLE DVD REGION THINGY.
Region Locking means grace for game producers.
japanese games also work on asian xbox 360.
