Could the 'Nintendo Switch Pro' just be a new dock?

In the end, this idea has been pushed around for what feels like years. Essentially... It's not going to happen, the USB port doesn't have the bandwidth necessary, it's also far to high latency.
And a dock that doesn't rely on the Switch handhelds internal capabilities is entirely redundant, you might as well sell it as a stand-alone home console that runs the current software library and be done with.

A big drive behind the move to a Pro and Mini setup is the fact that it's becoming cost prohibitive to use the X1 chip at this point - and they've blown through the ~20M that were stockpiled and are having to mass produce them again.

We will definitely see an updated chip with better battery life and matched performance for portable (Mini), and one that maintains current battery life, but improves performance for docked mode (Pro).

Exactly, they'll be moving to the X2: http://gamrconnect.vgchartz.com/thread.php?id=226632

Double the battery life on portable and double the power docked, we will call it the Switch+
