>WiiU console and WiiU tablet controller not connected to each otherYou're not making sense. This is a feature directly built into the devkit that takes almost literally no effort for developers to implement. This is in no way comparable to any of the things you listed, especially because those require customers to have two pieces of hardware, You might as well be saying that you refuse to believe anyone will utilize the L button until the console comes out and we know for sure

Eh. The problem in quite a few wireless features is the amount of data being forwarded. If the console itself has to do the processing, what can and cannot be done with it is purely dependent on specs. If there is some kind of transmission between the console and the viewing device (screens, controllers), the data has to be transmitted. If the max limit of data transmitted is achieved, we'll be in deep trouble..
What I'm trying to say is that we don't know the hardware of the console. Hell we even know that the hardware has changed between different showcases. Being pessimistic never lets you down
