Wasn't going to bother posting this presentation, but a high quality recording recently surfaced.

Skip to about halfway or so if you want to get straight into the game. It's still a 20 minute video with about 30 seconds of combat and 9 minutes of bunny hopping.. but what is shown definitely looks smooth. Cant complain about what I'm seeing, just wish there was more of it.
Limit breaks seem interesting, but if its just a timed bar that you build ala FF7 then there better be some kind of skillchain-esque system added as well. We expect there to be, just hoping it wasnt replaced with Limit breaks.
Reason for continued optimism: check. Whether that feeling survives GW2 is another question.
