Retailers often set a date on products. This date has nothing to do with reality, its just random.
The game is still in alpha. Once a beta is approved, it will be 3 - 6 months until the game releases. That means that even if a beta was approved tomorrow, we'd still not see the game until the May - August time frame.
All we can do is wait for them to approve a beta, then we'll have a better idea of a release date.
But yeah, to quote Johan : "Q1 isn't happening".
