I think it's possible, but I don't know how long Nintendo will want to push the Switch for, if they try to cut its life short with a successor like the GBA-DS it won't.

Couldn't that be counter-balanced by the fact that Wii's sales were """"mediocre"""" for the last two years? They pretty much did cut the Wii it just wasn't intentional. 

Well, that would be akin to the Wii U being released in mid-2010 rather than late 2012.
