I'm optimistic of the success and quality of Switch and games, but I have no reason to buy it day one despite how hyped I am.
I've followed the Switch since early NX days. But, I only really want it for local multiplayer. I already can play Mario Kart/Smash on Wii U, and Snipperclips/other games are coming to other platforms.
So, Arms (and then Splatoon 2) are really what I'm going to buy this for. By June GameStop and other companies should be selling bundles anyway. Hopefully there's an Arm's themed console coming! Very excited for that game above all others.
