Nintendo wont even consider it.
The man in charge of Nintendo has stated he feels the same way as the founder. Nintendo wants to be simple and fun, with gameplay as its focus. This means, graphics and secondary features are not really a priority to them.
Nintendo has always been about being different and they will NOT copy another consoles idea. Why do you think they were so stuck on cartriges over cds, because it was being used by other consoles. It took them long enough to realise they would not get many third party publishers with cargriges anymore and they could save a lot of money by using cds and dvds.
anyways, nintendo doesnt care and wont try to match it with a similar product. If they do anything, it will be completely different. Right now though, they dont need to as their main selling point is the wiirote itself.
