Bit of a shame you can't just pause the game, but it sounds like they'll be working on that.
It does sees a little daft to me that there is no incoming call alert for when the console is off, but presumably connected like with Wii Connect 24? It would've been nice to have the thing work as a full videophone, seeing as it clearly has the tech to do it.
All in all though these are certainly not major issues, as some of the big N haters will try to make them out to be.
Roll on launch day.
