As mentioned in another thread, what Stephen Totilo of Kotaku wrote:
I can see Nintendo at first vouching more for Unreal Engine 3 than its successor, as many developers know how to use this engine, and if they have current projects utilizing it, then it bodes well for ports of various kinds. Though for Nintendo to actually not support Unreal Engine 4 would be an unwise decision, as that engine will most likely be, as others have suggested, the most licensed engine next generation. And once developers start to jump shift in 2013-2014, who would want to stick around with eventually arbitrary tools just to have their games for Wii U as well?
