Like I said, Nintendo just needs to have bundles, maybe different colours and a couple of price cuts to help the Wii along in sales.
Most people who wanted a Wii have one by now. The so called 'casuals' aren't going to want to buy a Wii because of a hardware revision. It's the games/bundles, colours and lower pricing that will interest them.
As for the core gamers who look down on the Wii, they're not going to want to buy a Wii for hardware revision either if they already have a PS3/360. If they didn't want to buy it for the games before just because of 'weak graphics', a revision probably won't change that.
How many current Wii owners will go out to buy an HD Wii so they can see jaggies more clearly?
It's best to leave it as it is until it's time to move on (which is not far away). Then they can address the weaknesses of the Wii properly with the new console.
