Nintendo releasing an HD compatible Wii makes about as much sense as the United States Democratic Party funding a 100,000,000 dollar reenactment of Battle of Stalingrad; yeah it seems like a good idea for the Russians, but how does this make benefit Americans?
If Nintendo is releasing an HD compatible system, it will certainly be a brand new system, not an update to an existing one. I would expect the next Nintendo home console is about a year and a couple of months away.
I describe myself as a little dose of toxic masculinity.
