GDC 13: Frostbite 3 and UE4 not supporting Wii U

'We have Unreal Engine 3 for the Wii U,' says Mark Rein

Unreal Engine 4 and Frostbite 3 will not be supporting the Wii U.
As reported by Kotaku, despite having previously announced support of Unreal Engine 4 for PC and PS4, and today revealing it will also be scalable to mobile and HTML5, Wii U developers will have to continue working with Unreal Engine 3.

In a Q&A session at GDC, Rein explained that Unreal Engine 3 development would not just disappear because it had released UE4, and that its latest engine was designed for next-gen development as far as consoles were concerned.
"We're not… we have Unreal Engine 3 for the Wii U. Right?” said Rein.
“And Unreal Engine 3 is powering all kinds of amazing games, still lots of games are being made with Unreal Engine 3. We announced today about a new Unreal Engine 3 license. Unreal Engine 3 doesn't disappear because of Unreal Engine 4.
