I think they should add like 2-3 more races if that is feasible. That would give the game a lot more flexibility, especially when all 6 races are playing at one time. I doubt they could do that though. If they can then they should come out with SC2. If not they should come out with a massive expansion. SC is still popular, they'd still get a lot of money out of SC. I wish they would make more sc stuff.
