Well, extra joycons connect.
But it do not docks into TV. But is because of it doesn't fit on dock? Could it transmit to TV in non official docks?
Seems it was not designed to force the clock to dock levels, it might not have a cooler.
But could it stream at 720 to the TV? A posterior software update could allow it?
Would be neat if they eventually release a mini dock (sold with a joycon pair and a grip) that have trais for charging the joycon. It would allow to have the full switch experience with the lite version.
But maybe the marketing message would be more complicated to do it now.
