Initially my guess was 80-85m but I can see 100m being plausible due to the fact its a unified userbase, Vita users coming on board, likely to have a longer life on the market, no portable competition and the fact that right now they're selling it like a console which down the line I can see change in approach when they cut the price and begin selling it like a portable to fully migrate the 3DS and Vita userbases over.
It would be late late into the platform's life should it pass Wii though and likely in the phasing out period of the platform's life.
