Originally set to release in late spring, that won't be happening now, and we also don't have a set time period now. Over on the Touch Arcade forums, one of the developers (from Crescent Moon Games and We're Five Games) have posted the news and the reason why.
Apparently the delay is so the game can be ported to "other console platforms." What's even better news is the core development team is not handling it, a completely different group, Blowfish Studios, will be tackling the porting duties- meaning the main team is still focused on making the best mobile game possible.

I've been following and covering Morphite for a long time, and I would gladly wait for the game to get a proper work over than a rushed, bug-filled mess. I'm sure no one wants this game to pull a No Man's Sky, and wind up nothing like the promises the trailers made it out to be. I trust the developers to get this done, and get it done well at that.
