Maybe this isn't precisely a pro house in the Korean sense, but it's pretty damned big news. Fnatic and Root are coming together in Florida to have a practice house of sorts where they'll be practicing SC2 8 hours a day. This is pretty big news. Catz and Drewbie have been living together for a while, and ROOT.SunDevil has said that SC2 practice was definitely a consideration for them moving in together. I think they've both been improving recently, but with two more top North Americans living with them, they should advance much more quckly.
Honestly, I'm super excited to see what comes out of these guys. I've never been a big follower, per se, of any of their careers, but now I will be.
