From the FB page:
As of today, we are still projecting a launch on iOS and Android later this month and confident that we’ll hit it. We are doing our best to be a launch title for PS Vita in February, and the Mac version will also release then. The 360, PS3, and PC versions will be released at the end of March. We’ll use this extra time to improve the game and address as many of the comments that you’ve given us as we can. Please help spread the word about the game if you like what you’ve seen. For The Pinball Arcade to be successful and continue delivering tables for years to come, we’re going to need a lot of help getting people to notice us."
Have a sense of dread that this game won't take off and DLC will be cut off within 3 or 4 months, but I'll hope for the best and try to get as many people as possible to check it out.
