Rumour - Wii U hardware development troubled

Whispers say Nintendo is struggling with the development of the Wii U, finding its tech unable to deliver on some of the system's core features.

An alleged source inside Nintendo told the generally reliable 01net that the Wii U's final architecture had been uncharacteristically "rushed out the door", and that its chipset isn't powerful enough for what's required.

Notably, engineers are said to be struggling with getting the wireless tablet to work despite three prototypes, with a fourth expected this month. Currently, dev kits are said to require a tethering cable.

Even tethered, the source claims communication between the console and controller is shaky, and developers have been plagued with near daily software updates.

Although the console was reportedly internally scheduled for a June 2012 release, Nintendo is said to be considering pushing it back to September 2012.

01net's source is the same to have spurred talk of a second circle pad peripheral for the 3DS, something which is rapidly looking more and more likely.
