We were talking about the XBox One not the XBox 360 (which I agree has been strung along forever since Crave went bankrupt).
Farsight announced that they were in fact going to make an XBox One version of the game in their newsletter #26 sent on April 11th quoting a mid-summer release. Before that there was a lot of doubt whther they would make an XBOne version at all after what they went through for the XB360.
"If you've been paying attention to Microsoft's ID@Xbox initiative you might already have caught this, but we're proud to announce that we have been hard at work on the Xbox One version of Pinball Arcade! We're expecting to launch mid summer 2014 with the entire Season Two collection. "
The only reason I'm keeping up with the news on the XBOne version is because they are delaying season 2 for PS4 until 30 days after the XBOne launch to meet with Microsoft's new indie publishing policy (which apparently saves FS a lot of money in submission fees).
