Despite all the naysayers, I think this is going to be a seriously sweet FPS. People need to stop thinking of Half Life as "The only viable way to do an FPS".
NOLF2 took a very different approach than Half Life did, and it was (in my opinion) a way better game.
Unreal 2 is taking yet another approach (or so it would seem), actual large open spaces as opposed to the small straight corridors that was 90% of Half Life.
It did seem to play a little fast, but if this is built on the same engine as UT2003, there is undoubtedly a console command to slow it down
I didn't think the voice acting was all that bad, to be honest, and I liked the "What where all those 'donts' again?" bit.
I think this is going to be the FPS to beat for awhile to come
(Simcity 4 first though!)
