The problem is that we don't know other factors surrounding the RAM bandwidth.
Too many people here, and across the Internet, are makeing bold claims based on just this 1 figure. Well, there are several more figures that actually go into determining what can and cannot be done.
It's like looking at voltage. 50,000 volts sounds like a lot but will it kill you? Depends on the amperage. Regular static electricity shocks are over 10,000 volts. But just a few miliamps will kill you.
So all this bandwidth talk by itself is nonsense. We need to know the latency, we need to know a lot more about the eDRAM, we need to know more about hwo it's all connected, etc...
But the most interesting thing is that developers have already spoken highly of the Wii U's RAM, low latency and memory system. Go figure.
