I feel bad about missing the first event :\
If you're July event has a Gears tourney and/or Halo 3, I'd attend it in a heart beat. I'm always for some SSBB on the side, too...
As far as PC tournaments go, I'm a long term player of UT2k4 but your guys' rule sets this past tourney were ridiculous (just saying). :p I know you guys were having just a for fun tourney, but Plunge- no matter the game type, just is NOT a fun map for me. CoD4 and TF2 are always fun tournaments, though, and if you have some UT3 or Q3 or even Q4 tournaments (1v1), I'd love to do those, too.
I wouldnt mind a Gear of War pc tourney and not sure when Gears of War 2 is coming out ( thats pc too right?).
