Halo 4 isn't coming anytime soon, kiddos. Halo is an every three years title. 2001, 2004, 2007. That means we shouldn't expect the next one until at least 2010.
Additionally, I read a rumor somewhere that Halo 4 is not for 360, but it's successor, Microsoft's next console. Imo this means we might not see it until 2011 or later.
Regarding all Sony's "huge" titles, meh. I remember the Gamecube versus Xbox fight were all the GC fanboys kept claiming "wait till game XXX". Be that Starfox, Mario Kart, Smash Bros, Mario Sunshine, on and on.
My point is weird as it sounds, big games historically dont sell systems, and I dont expect PS3 to be any different. GT5 Prologue is already out in Japan and it hasn't made any difference. It's easy to see the same will hold true in USA for GT5P, and then the true GT5..and so on..
