Personally, I think focusing on BW would have been more interesting (as long as the APM limit still stands), but I guess SC2 is alright too. The fact that they're even doing this though makes me happy.
The reason I say BW would be especially interesting is simply because the game has remained basically unchanged balance-wise since v1.08 which came out in 2001. Despite that, the pro scene never left, and we're still seeing some shifts in the meta even today. It would be cool to see a strong AI flip the script completely for such an established and "well understood" game. Opportunities like that are kind of rare, at least when it comes to video games.
