I don't know if it's going to be the biggest across all platforms but this game is the main reason why I bought another Xbox 360. I can't wait!

LOL at anyone who seriously thinks the game will sell less than ODST.

What he said is probably right in fairness, of all the games launched on each plaform this year then LT sales at the end of 2010 will probably have Reach on top due to how front loaded it will be. Cod will sell more as a multiplatform title but not on 360 sales alone.

GT5 will not sell close to Reach first week, look at past sales trends of driving games, they're just not front loaded.

Wii is not a gaming platform anymore?

Pokemon HeartGold/SoulSilver want a word with him

GT5 will outsell Halo 3,COD MW,halo reach.not first week but will definetly over time.

and GTA Next is still to come in 2011

yeah, whatever. With Galaxy 2 and a Zelda coming out in 2010, no one else stands a chance overall.

First week sales, probably, over course of whole year, not a chance.

I'm sorry but nothing is definite until the game is released, it will be a struggle for GT5 to hit 10 million with such a lower userbase.  

MW2 will make it look silly in sales that much is a fact so not sure why you said it would outsell it.

I firmly believe that if they dont change the name to Halo 4: Reach they are losing 3+ million sales.

The problem with "milking franchises" is you isolate new fans form joining. Halo 1 2 or 3....its easy, somebody can go rent 1 or 2 catch up join in on the fun, it feel swhole its "main"...throw in halo wars, and ODST people see it dilluted, no Reach on top of that.

I think it closes people off from wanting in because it seems to encompassing in the universe, its not as inviting having all of these different games. I know they probably cant rename it since its a prequel, but i dont think this touches Halo 3 WW.

Big franchises moving form Gen to Gen for the first time dont suffer sales hits. MGS4, Halo 3....multi plat, former exclusive games, DMC, GTA, RE all show similar to the franchise roots dispite userbase.

Dont underestimate the sales only from playing a loved franchise on a new generation console.

The game is a new strand in the Halo universe, they need to go away from the numbered branding to attract new customers, the old cstomers will buy it regardless of whats in the title.  Also maybe they're saving Halo 4 for a game that has the chief return, call it a banker for next gen.
