Well, let's put 3DS at 100M and Wii U at 30M, so we got 130M for the PS4. Taking in account that the PS3 with all the problems and bad planning will probably reach 100M, it wouldn't be such a stretch to reach 130M with the PS4.
Besides that, expect the 3DS to take a hit from smartphones in the next few years. Right now they are already more powerfull, in 2 years they will be crunching it in performance.
