The Gameboy curve is so weird partly because the atomic bomb that is Pokemon reviving it in the late '90s/early 2000's. I was there and I know. I have clear and fond memories of that era, and I played Gameboy more than any other console during that time just because of Pokemon.
Anyway, I think Switch will be more DS-esque in that it'll have a slower burn and longer legs thanks to a stronger steady stream of games (1st and later more 3rd parties), more wiggle room in price slashes and bundles, as well as the simple fact that being part portable opens it up to a wider audience. I'm not saying it'll sell DS number, but I can see this thing lasting 8 years in some form or another, perhaps even ramping up in years 3 and 4, and keeping far more momentum than Wii did.
