Nintendo switch will use USB-C cables for charging

I think people shouldn't overhype USB-C and keep their expectations in check. Most likely, it will be USB-C over USB 2.0 with quick charging if we are lucky similar to how phones with USB-C connectors are... Maybe USB 3.0 if we are extremely luckly.

And I highly doubt it will have Thunderbolt since that is an intel technology which requires a licensing fee...

Oh and I doubt it will support external GPU
