yeah, in the past 3 months or so, many major games, across all consoles, saw delays - from halo 2 to final fantasy to metal gear to perfect dark, etc, etc. some heftier than others.
metal gear's release was only pushed back 4 months, notably shorter than perfect dark's 28.
not that any of this would matter to you anyway, since you're unwilling to own the game (let alone any of the other cube titles)
