The only things that really interested me were backwards compatibility and the new controller. Most of the games didn't really interest me and barely any of them actually showed any gameplay. Just CG trailers.
It's definitely a lot better than their past two E3s, but they still have a long way to go before they make me excited for their content. People are really overreacting to this conference, especially considering Sony and Nintendo haven't had theirs yet.
Oh yeah. They also showed a TON of ports and re-releases. Shows that there's a lack of games at the moment.
