I just returned from the kick off event from Microsoft for E3 2007 and they had some pretty cool games to show off including footage from Halo 3 and more. Microsoft also announced that all the games save one that they showed tonight will be available this year in time for the holidays.

As you might expect, Xbox 360 is getting most of the love, but Games for Windows also has some very interesting titles coming including a Piñata Island game and the Gears of War for PC. Microsoft showed off some Gears of War for PC footage and it looked fantastic.

One of the most interesting announcements for fans of Halo is a Halo 3 themed Xbox 360 that is pictured with this story from the brief moments it spent on stage before it was stowed away out of sight again. From what I could see, it appeared to be nothing more than an Xbox 360 Elite with a nice looking Halo 3 green paint job and a special wireless controller. Tomorrow kicks off the show in earnest, check back for more coverage of E3 2007!
