Crytek's Cevat Yerli has recently said the company are very happy with WiiU's hardware capabilities:
"As for the latest round of tech that we do know about, Yerli may not be particularly taken with the PlayStation Vita (Jones is more diplomatic, and says Crytek will work with the machine when the timing is right and the interest from licensees is significant) but he's excited about the Nintendo Wii U.
The specs are very good," Yerli enthuses. It's a challenge for designers, but once thought through it can add value, and that's what ultimately important. Our guys in Nottingham they are very happy with their tests on the dev kits and they're excited about it."
In other tech related news, this rumour is now doing the rounds:
"I know a person who is an investor of MoSys and other technological companies, we talked about Wii U a few days ago and I became surprised with a comment from him about the new console:
"Wii U uses 28nm manufacturing process from NEC and 1T-SRAM from MoSys"
I asked him how he could know this and he told me that this information has been shared to the investors of MoSys, because the Nintendo partnership is an important one for them and any signal of losing the deal can be very dangerous for the health of MoSys business. Since he isn´t a technical person I didn´t ask him about technical specs, but the 28nm comment was very interesting."
Interesting..I expect Nintendo will wait till GDC to go official with any specification details - this is all rumour and should be taken with a pinch of salt.
