You left out Foraz 2, Colin McRae DIRT (demo available in europe today), Splinter Cell Conviction (go look at the ubiday HD trailer), Project Sylpheed, Two Worlds, FlatOut Ultimate Carnage (best arcade racing game imo), Blue Dragon, Lost Odyssey, Turok Next-Gen, Haze, Alone in the dark 4, Kane & Lynch, Endwar, Naruto : Rise of a Ninja, Trusty Bell (Eternal Sonata)..........
There's sooo many highly anticipated games coming on 360.
You should try out the japanese Tenchu Z demo (and dl the Trusty Bell one), but, I must warn you, it is quite bad...
