Strap a “Halo” name on something and it’s likely that it’ll do pretty well, and Microsoft is confident that Halo Reach will be the biggest game of 2010, at least according to Microsoft’s product management director Aaron Greenberg, who also finds the time to diss Gran Tursimo 5 a bit:

“Is it launching next year? I’ve seen years and years of minigames, but I haven’t seen that the game’s done. They just released the PSP version — maybe that’s what they’ve been working on.”

Halo Reach will have plenty of competition, as StarCraft 2, God of War 3, Rage, Alan Wake, Heavy Rain, Bad Company 2 and a ton of other anticipated games will be released in 2010.
