Colin Kelly from Celio Corp has posted on the WMExperts forum to check out the website at 11:00 am today for an announcement!!
I have no idea what it is.
I have a few guesses so lets see how my predictions go (in order of how likely I think they are):
1. Even lower price and/or extended the pricing program which ended yesterday.
2. BB support
3. iPhone support
Slide SlingPlayer support in between 1 and 2
