Of all the games people listed, in terms of 2009, I only see Halo: ODST and Alan Wake moving hardware. (assuming the latter releases in 2009)
The listing of the multi-platform games is near negligible because they are MP. Also, with games like MW2 and AC2, I imagine most of the base for that crowd already owns a system. I have similar sentiments about Forza 3.
As for games like Risen or "untitled future game", way too early to tell. It would be best to make this thread after E3.
