I know i'm still impressed. The 360 looks promising and the Summit only backed it up. MS has suprisingly strong support from the Japanese developers (assuming it's real support) despite the fact that the 360 itself isn't getting much support from the Japanese people.
PGR 3 looks mind-boggling good. I honestly can't wait for it. All the games showed at the event looked clean and all the clips appeared to be rendered in real time without slowdowns.
Looks like MS is lined up to break into the japanese market and i'm hoping they do. This time MS has a lot more then just Team Ninja behind them.
Even thouh Team Ninja didn't annouce Ninja Gaiden 2 for the xbox at the event i think it'll still be an Xbox 360 game. Itagaki-san has been very clear that he only wants to develope for one console so they can focus on making the game and not worry about porting. Given the fact that DOA4, DOAX2, DOA: Code Cronus and a new Team Ninja IP have been annouced for the 360 i doubt that they would switch to the PS3.
