Nintendo has the best first party exclusives.
You don't buy a nintendo console as your sole system. It's your second or third system.
Zelda will probably be a game of the year contender. Mario Odyssey will also be one too. That's enough to sell me on the switch.
I basically don't want to miss out on anything. For me it's PC>PS4>X1>Switch.
Mario games never disappoint, same with Zelda. I'll be enjoying my Switch and Zelda on March 3. Then it'll collect dust until Mario. It's like the Wii U (which has some amazing exclusives).
It's bad for nintendo, but good for those that want it all. And, I want it all
