You know I think that the HD rumble is blown out of proportion. They said the controllers won't have it. IF the controllers are connected to the main unit, it would make sense to move any HD humble into the center of the unit. or possibly on the edge of the screen if they wanted to still give you 2 HD rumbles for backwards compatibility. But something tells me you probably only really need one.
As for the not being able to be docked, this doesn't make sense. Doesn't the Switch only Dock via a USB C port that it also uses for charging? If that Is true, it makes no sense to cut that feature. However. like everyone else said it would make sense to not have it come with a dock. The form factor might make it impossible to dock with the current docks, however, they could just give you cord that does the same thing as a dock.
I have to say I am very interested in the mini model, and I hope they don't do a Pro-model this year. I think the Switch Mini could propel the Switch into the portable realm and help Nintendo for another year or 2. Then they could properly make a more powerful Switch Pro closer to the competition's new consoles.
