Definitely Hockey, Mens and Womens.
Curling, I love Curling.
A Few Others to keep me occupied until UFC 110, WIll they allow you to wager on anything else? I figure all of the snow events Sking, Snowboarding, Luge, Skeleton, Bobsledding, Moguls, Biathlon (Norwegian Drive-by), Ski-Jumping would all be really hard to wager on. I will shy away from Figure Skating b/c A) Anything where the scoring is purely in the hands of humans I will not wager, at least in other sports like MMA, and Baseball, the officials/ judges calls are only a part the game.
