The above has a detailed summary of the changes that will occur.
Will pokerstars still have the vast amount of volume? do you guys see yourselfs focusing on alternative poker clients? It is kind of a kick in the balls to 2016 goals >.<
I think there's a decent chance that we see them give back a bit in 2016 to SNE and/or SN from the original announcement.
If that doesn't happen, things get interesting. I think higher edge pros should still likely play PokerStars some of the time minimum. Lower edge guys and some of the other pros might find mixing in other sites a good idea. Games are higher edge there, and if you load up enough poker rooms you'll get decent action.
