When I saw the demonstration it blew my mind, it was everything the wii mote should have been. JoyCon is a much, much, much, improved Wii-Mote, it works whitout the IR Bar so it can be used in any use case of Switch.
I think this is the killer hardware for Switch. I don`t even care much about Nintendo software, but this piece of hardware is truly exciting.
Hardware has been boring this whole gen, with the exception of the PS4 Pro, they were just low specced PC`s with some exclusive games to market themselves. Ps4 may have some great games but it`s hardware is boring, the same for XB1, but JoyCons are really exciting.
