Since the Magicka wizards didn't know what to do with themselves once their unemployment extended into the thousands of days, they decided they'd just get back to doing what they knew best.
Magicka 2 was announced at the Sony press conference, along with a somewhat humorous trailer and the tagline "Learn to spell again." It's being developed by Paradox, and is coming to the PS4 and PC. Other than that, not a whole lot was said about this one yet. But, I bet there will be some more wizards.
