One thing I really like is how while other's make games gear towards online, Nintendo is instead opting for a similar route as Pokemon GO. Enabling people to meet up.
Wouldn't surprise me if there'll be Switch-picknicks of sorts in parks here and there. Especially Japan. People showing up, blankets out, then enjoying basically a LAN-party of Switch-screens.
One thing I think they should'v gotten right from the get go with the WiiU is how much it feels like a jukebox console. A console I can play for example almost every Zelda created, likewise Metroid and Mario games. The game-touch-pad wasn't put to much use beyond the gyro controls for me, but the gaming library certainly has.
By the way. From software supporting Switch. Hope that means Demon/Dark souls. And with Grasshopper studios, REALLY hoping for more No More Heroes, or why not a Killer 7 remake
