I don't know if the Microsoft presser was a letdown... Most of the games they did show had actual gameplay and weren't just cut-scenes like I was expecting. The only letdown for me was they didn't do a Q&A but after the bad press they got the past few weeks I can hardly blame them.
They didn't do anything to make want to buy it though.
