I think many guys want to Switch sell and cover PS4 sales as a measure of success and this is a mistake as they are consoles with proposals and very different public. At the moment guys, the Switch has to at least be equal to the 3ds + wii u sales, since it has united its two fronts, to become a success. This is the current target market for nintendo, not the market that sony achieves.
If Switch already sells more than 3ds monthly, there is a bright future.
