To know how the Switch will sell we had to wait for OCT, NOV and DEC, and also the first month of the next year and the support of third party developers. By know im not have optimistics predictions cause of the price of third party games, low storage on cartridges of games and low internal storage for installing huge amounts of data necesary to play some games, its not confortable to some traditional players and more expensive that just buy a ONE S or PS4 and play with more quality and less money (Im not to much into portable gaming).
My predictions... PS4 around 120 Millions... Switch around 40 to 50 millions... One 40 to 45 Millions...
I kwon im soo pessimistic with Switch, but without a great support of thirds parties and the reduction of handheld market in the recent years i dont believe that the console will endure with a great average of sellings for many years, you have to remember that the third parties has to expend more money to give less appealing versions of its games on switch, just with the appealing of being on a handheld. Wii U suffered the less support of thirds and ended diying soon... Switch has a really better numbers than Wii U, cause of that i think it will sell better than One or Wii U but not that much of Wii, PS1 or Gameboy.
