Mass Effect and Bioshock are 2 exclusives that look very good. Assassin's Creed and Army of Two are cross-platforms that also look very good, but when you want a cross-platform game, the cheaper option is the best.
I love my 360 the online experience is what keeps me involved. The constant demos and other online stuff and the simplicity to play with a friend instantly is what helps it.. I have no exp with PS3 but we will see how that goes.. Wii i can't wait to go home and play on sunday.
You guys did read yesterday's DailyTech article on the new cooled 360, right? http://www.dailytech.com/New+Xbox+360+Cooling+Hardware+Found+in+Europe/article7667.htm

360 is just like any other MS product. Looks great, but unreliable. Has some good games so if you are going to go for it I would highly recommend you buy the extended warranty.
