Jeremiah Slaczka, the CEO of Scribblenauts developer 5th Cell, has stated that the Wii U is "definitely more powerful than Xbox 360 and PlayStation 3," adding that he finds the argument over the console's capabilities "frustrating".

Speaking in the latest issue of Game Informer, Slaczka said that the Wii U is "definitely more powerful than Xbox 360 and PlayStation 3. It's kind of frustrating to see the rumours and speculation of people going back and forth saying it's weaker or more powerful. It's definitely more powerful."

5th Cell is currently developing Wii U title Scribblenauts Unlimited, the fourth game in the word-based puzzle action series.

"I think we were one of the first developers to see the Wii U," he added.

"Nintendo came to our studio and demoed it to us. A couple of weeks later Warner Bros. got to see it, and we said we should do this. This game was originally a Wii title but later moved to Wii U. It's been about two years in development."

Developers can't seem to agree on how powerful Nintendo's upcoming console is.

A report published yesterday quoted Tekken series producer Katsuhiro Harada as saying "the [Wii U's] clock is kinda low," and that the console's CPU was "a little bit" slower than 360 and PS3's.

Harada is currently porting arcade fighter Tekken Tag Tournament 2 to Nintendo's hardware.

The debate over Wii U's power has raged for months, with regular conflicting views from developers and publishers.

"It's not up to the same level as the PS3 or the 360," said one developer speaking to GamesIndustry.biz. "It doesn't produce graphics as well as the PS3 or the 360. There aren't as many shaders, it's not as capable," said another.

We have no idea who to believe.

Earlier this week, Epic Games' Mark Rein told VideoGamer that it was not Epic's "intention to bring Unreal Engine 4 to Wii U", but that a licensee could "port" a UE4 game to run on the console if it wished to do so.

Unreal Engine 3, the engine used by many Xbox 360 and PlayStation 3 titles, "is a really good fit for that platform," he added.
