Like, just now I put my phone down after reading some responses, picked up the grip with the joycon attached (I'm laying down on my couch) and I'm holding the controller very normally upright with the face buttons facing me and the top of the controller facing the ceiling, you know, a completely normally way to hold a controller, and in a menu I've already had it not register two of my inputs and three of them were delayed.
I hate hate hate giving you guys bad news like this because god damn this system is awesome in every other way but this connectivity or sensor problem is really bumming me out :/
Edit: I see some people thinking of cAnceling their preorders and man that was never my intention with these tests. The console itself is rad as hell and I can only imagine Nintendo HAS to have some sort of fix for this. The only reason I did those extensive tests was to be as transparent, and so everyone knows what the CURRENT state of these consoles are. But yeah ok really hoping that there's some sort of statement and more importantly a fix, cause gah dahm dat Zelda.
