WiiU is 2 years old today, how much do you expect it to last?

I think the next Nintendo consoles will feature a unified platform (architecture, online and so on), but still a home and handheld console. The only issue would be that Nintendo will likely go with only one physical media type. So this would mean a cartridge (for the sake of making it easy for the portable). Then should the home console feature a disc drive? If it did it would only be there for the sake of backwards compatibility of disc based Wii and WiiU software. Of course BC isn't a requirement but has been a nice feature for both the WiiU and Wii in the past, and consoles of other companies.
