My prediction? Prepare to be disappointed in how slow Blizzard always is. I'd like to say it'll come out in May, but it could just as easily be August. Going from announcement to release before April, for Blizzard, is impossible. They could increase the size of their development team a thousand fold but they'd still sit on the game "until it's ready."
