The 360 will continue to have some wonderful exclusive titles at least through to 2010 when Mass Effect 2 and Bioshock 2 are released (not to mention Halo 4 and Perfect Dark 2 somewhere in the middle there). Things to look forward to between now and then include at least a year of slightly superior multi-platform games, the next Viva Pinata, Too Human, BK3, Fable 2, Gears of War 2 and maybe 3 in 2010, Alan Wake, new IP, PGR5, Forza 3, and the probably excellent Kameo 2.
