one WCG tourney.
one blizzcon tourney
they might add a ladder stage and try to get someone to broadcast it for them while paying royalties to blizzard, but thats a big if.
besides that, blizzard will NOT invest into the future of e-sports in NA. there is just too much risk of failure. in no way is pro gaming mainstream enough to gamble building an infrastructure where there are constant seasons of leagues, proleagues etc etc going on.
we are fucked.
