Honestly? I would be very very disappointed with them.
You have this company that decided to step up and try something different, something daring, something that not any company have ever did in years! AND THEY SUCCEED! They opened the market to more gamers and gave companies more ways to inteact games.
If they did release a HD wii that would only mean that they abandoned their principles and became "just another brick in the wall". That's more or less what happened with the SNES: Nintendo was doing fine if not great, but the newcomers, SEGA and NEC released their consoles and faired well, Nintendo abandoned their NES and create the SNES just to fight with them, losing the half of their userbase..and only to prove the companies they were "cool"..
I doubt they will. Iwata has another mentality..but if they do..it would be very sad.
