How many German consumer electronics companies are there? It's silly to say any German company can produce a console - anyone can produce a console buying US designed CPUs and GPUs on a Taiwanese motherboard to play games. A console needs to be a fully realised platform, including OS and services and games. That's why Ouya and every other new player just fails.
The hardware is fairly immaterial to the job of playing games unless one is beholding to the antiquated romanticism of 'proprietary hardware'. The realities of the console business and pastimes are based in economics and creating affordable experiences. The days of esoteric hardware, the golden age, the likes of the Amiga powering past the typical computers of the time thinks to forwards-thinking, unhindered design and custom hardware, is way, way behind us. All freaky hardware does now is get in the way of the developers creating their games. Cerny identified this and very sanely chose not to do something stupid like split pools of RAM with tiny, super fast RAM. And if we look at the modern gaming landscape, the full glut of indies as well as the AAA megacorps, we see far more variety in actual games than ever before because of the homogenisation of hardware and tools. Devs are wrestling less with getting triangles on screen and more with game design and balance and ideas. Whether console games are pioneering or repetitive is down to the dev and pub choices and not the hardware, but having simple hardware eliminates that barrier and gives more opportunity for devs to try new stuff.
If, hypothetically, there was a magical new tech that'd be vastly superior to the PC designs on offer that if embraced by devs could provide a whole new world of gaming, then yes, it'd be somewhat amiss for the console companies to ignore that tech and give a watered down experience. But there isn't. Karmaprof's desires are for a fantasy, and no company on Earth, not from Germany or anywhere else, can make that happen.
