Unreal Engine 4 is Epic Games' impressive next-generation engine, which can help developers deliver more impressive visuals when making their latest titles.
It's being geared towards the upcoming PlayStation 4 and the next Xbox, both of which are expected to have plenty of power under the hood.
Recently Mark Rein, Vice President at Epic Games, said Unreal Engine 4 would not be something Wii U gamers can look forward to, saying if developers want to ship Wii U titles they can use Unreal Engine 3.
However, he's now backtracked on this statement in an interview with Engadget:
You heard the stupid gaffe yesterday about the Wii U. If someone wants to take Unreal Engine 4 and ship a game on Wii U, they can! If they wanna ship an Unreal Engine 4 game on Xbox 360, they could make it happen.
Unreal Engine 4 is scalable technology, therefore should developers wish to use it when developing Wii U games they can - though naturally the visuals would be compromised as a result. It's fair to say Epic Games certainly won't be using it for Wii U, but that doesn't mean others won't.
