Coming from an HD Warriors interview with Shin'en's Manfred Linzner...
On Wii U having enough power for years to come
‘We only know you need to treat the Wii U differently then those consoles because of a very different and in our view more accessible architecture. There is a lot power to unleash in the Wii U. Enough power for many years to come, at least from our point of view.
‘We know many people see us as Wii U experts. That is because we got a lot of technical praise for Nano Assault Neo but it’s not well deserved. Only very tiny bits of Nano Assault Neo took advantage of the Wii U architecture. We had the game from start in 720p at 60fps. We drew the complete game world twice for TV and GamePad. We had tons of overlays, special effects and even camera streaming and still had no GPU or CPU problems. So we simply had no reason to dig deep into the architecture. We didn’t expected to be seen as the spearhead of Wii U graphics as it undeserved, when looking at what the Wii U can truly achieve.‘
