I'm guessing Magicka 2.

Weve been told its not a port, and its not more DLC (which Magicka already has a huge amount of on Steam.) The stars seem to point to a potential Magicka 2, or perhaps some kind of spin-off in the same universe, with different gameplay.
I got a look at Wizards of the Square Tablet at PDX Con, which was quickly discarded from my mind into the nearest Icelandic memory recycling bin when I heard it wouldnt be coming out for PC. Since we know it isnt that, it has to be a brand new title. One of the only other things we know is that there are some ex-DICE guys working on it, but we shouldnt expect something FPS-ey, despite the Battlefield pedigree.
Well be in the GDC trenches to bring you more details from Paradox as soon as we can get our Frost/Fire Tentacles of Journalism on them in just a few weeks. What would you guys like to see out of a potential Magicka 2?
