They don't need to do much to "beat" microsoft, other than the Final Fantasy announcement, they really didn't have much :/ a good 80% of they're presentation blew chunks xD They just spewed sales figures and announced a ton of new games that "might" bring in some casual gamers :x
Sony could do more of the same, just show off titles we already know about, and maybe announce 3 that we haven't seen. That sadly would be enough to topple they're presentation >_> I have a feeling we'll get a bunch more info on....
Gran Turismo 5
Team Ico Project
Naughty Dog's project
