Dogs + Wires = A Bad Time.
And while Wavebirds are a godsend, they do lack rumble, as well as a Home/Capture/C button; and they're not rechargable. Plus these work in handheld mode without any sort of 3rd party adapter needed too!
If you do decide to get the console, and you'd like one in time for launch, in case you can't pre-order one anywhere, it's looking like I'll have a spare Switch 2...
I'm glad to see that the pre-orders have opened up more generally for the GameCube controllers though.
