At least six games were teased in the trailer for the system being Skyrim Remastered, an untitled NBA game, Zelda: Breath of the Wild, a currently unnamed Mario title, and what appear to be enhanced ports of Mario Kart 8 and Splatoon.

I personally can't say if Nintendo knows what they're doing this time around, but the concept of the Switch is certainly promising and quite unique. I just hope that it has a decent battery life. The Nintendo Switch will launch in March of 2017 and I assure you I'll definitely be one of its early adopters, but until then, I'll be seeing you.
