www.doomworld.com is one of the best Doom sites out there, IMHO. I haven't checked in there myself in quite some time, but they should have most of the latest & greatest info, plus lots of speculation .
I find I've lost a lot of my former interest in the FPS genre, though I recently tried Quake 3:Arena and had a pretty good time. One thing you've gotta credit id -- their engines have a great quality/performance balance.
