So is there any news about new sets for 2010? How can I get belle and snow white promos now? Anyone have them to trade or buy?

About Belle and promos: Some people have managed to get them from regular booster packs, but they're even rarer than the SR cards. Otherwise, you have to find a league near you, or go to conventions to participate in tournaments.

New sets: No new sets have been announced at this time.

Trading for promos: Check out the Agrabah bazaar, someone might have some to trade.

Look around the forums next time. Chances are, your questions are already answered somewhere.
