Midway is bankrupt.
They claim selling the MK licence is a "last restort", but at this point who knows what will happen with all the shady stuff that's been going on under the table with regards to Midway's finances. Check out the big backlog of Midway stories on Kotaku.
I never was a fan of 2D MK games personally, and the only 3D one I've played was MK Vs DC, which I rented purely for comedic value. It didn't dissapoint.
