The Wii was designed for a 5 year life cycle which means 2011 would be the earliest year Nintendo goes HD. But with the current popularity of the Wii SD this date may be pushed back a year or two. I don't think Nintendo will have to introduce the WII HD until the competitors start to equal or surpass their sales in a significant manner. The PS3 is down 29 million units it will take a few years of Uber stellar sales EVERY MONTH just to close that gap and the 360 isn't much closer. I think Wii sales will start to slow over the next two years because its Lo-Def design will start reaching saturation but sales would have to stop today in order for the competition to surpass it during its design lifecycle so I don't see a need until 2011.
