I say March 2011 because it will be about the time people will be getting tired of Halo Reach and want more. I believe that the later it comes out the more polish it will have no? O and I want berserkers again :D

November 2011. I hope Epic does a Beta for the multiplayer though, it needs it.

it's gonna come this year. I don't see why people think it's not

March 2011. Need time to beat all the 2010 titles.

This year already got Halo, which gonna be the 2nd biggest game launch in history (after MW2). But the biggest for 360, since Halo Reach will sell more than the 360 version of MW2. So i don't think its gonna come this year. They gotta save some goodies for next year, since next Xbox is probably gonna come in 2012.

On the next Xbox, so it can once again blow my mind. Gears of War 1 was one of the only games to do that this Gen. Would be great to see that happen again.

Lost Planet 2 = Gears 3 ... i kid... next xbox would fit for a rather nice launch title.

2001 - Halo
2004 - Halo 2 (3 years later)
2006 - Gears
2007 - Halo 3 (3 years later)
2008 - Gears 2 (2 years later)
2009 - NA
2010 - Gears 3 (2 years later) Halo Reach (3 years later) OMGS
2011 -

Microsoft isn't gonna release two of there biggest games in the same year. They are already claiming Halo Reach best game of 2010. It wouldn't make sense what heavy hitter would they have for 2011?

Asap please
