Finally able to unveil some stuff the MLG_Adam (@MrMLGAdam) and I have been working on with a bunch of other folks on the MLG team and the community.
Orlando will feature a couple of significant stream improvements:
1) Less Downtime, More games on Red and Blue channels.
A lot goes into getting a match onstream, both technically and in terms of scheduling. It isn’t possible to eliminate all downtime, but starting in Orlando we will be implementing changes that will significantly minimize it.
- We have added matches to the schedule of Friday and Saturday’s Main Stage matches
- Two extra computers have been added to the Main Stage[LC] to reduce setup time.
- Match start times have been staggered based on the Station at which they’re going to take place
2) 2 MORE Starcraft Streams featuring Community Casters and Open AND Championship bracket matches. Cast right from the tournament floor, there's now even more action that you won't be missing!
- This is a beta. For now, the two beta streams will be available only to Gold and Silver Members ( http://majorleaguegaming.com/membership ) and those who have purchased an MLG Orlando HQ Pass.
- All matches on these streams will be solo-cast by community casters Adebisi (@adebisiSC), Nerski (@VPnerski), Tumba (@TumbaSC), and Robin (@Robintivo).
- The casters will choose matches on the fly over the weekend, based on what’s happening in the bracket.
- For this Beta, the two streams will be available only in Medium and Ultra qualities in the MLG player.
- These streams will air all weekend long, exactly as the Red and Blue streams do.
- The Red and Blue streams will work the same way as they always have: available to everyone, with HQ available only for Members and those with HQ passes.

Enjoy!

Edit: couple of clarifications.

Definitely going to be higher expectations for the stream at Orlando, and I'm thinking they'll deliver. The only real problem I ever had with the MLG stream viewer experience was the downtime, and now that'll be fixed ;D
