I'm in for a Switch at some point for the games alone, same as Wii U. Xenoblade 2, Zelda, and Mario are enough to sell me. That said, I'll probably try to hold off on buying one at launch. The $300 price is very deceiving, you'll also need a huge SD card if you want decent storage, a $70 controller (not using that grip thing as my main controller), and of course a few games.
The storage it comes with is pretty laughable. I still buy all my non-PC games physically so it's not a huge deal to me but any chance of a digital future with Switch is dead in the water considering the storage situation.
