Nintendo held back publishers from showing some in-development Wii U games during E3, according to a report issued by Hit Detection, the game consulting firm founded by former Newsweek journalist N'Gai Croal.
The only third-party Wii U game playable at E3 was Ubisoft's Ghost Recon Online. Ubisoft also showed Killer Freaks from Outer Space, and there was a highlight reel showing during Nintendo's press conference, later revealed to have been games running on Xbox 360 and PlayStation 3 hardware.
"Developers have underclocked development kits, and worked hard to deliver titles running on that hardware to demonstrate live at E3," reads the report. "However, due to titles not looking much better than what is currently available on Xbox 360 and the PS3, Nintendo decided late in the game to not show those titles and focus instead on tech demos."
Ghost Recon Online was the only "game" shown for Wii U. Everything Nintendo was declared experimental, albeit with the caveat that some or all could actually turn into proper games.
It's unclear whether Nintendo's alleged decision to hold back games that wouldn't show better than existing releases suggests Wii U is, in fact, may be more powerful than both. Nintendo hasn't released proper specifications for Wii U, as has been standard operating procedure for the company for years, instead focusing on what's possible, not the literal guts inside the box.
