I believe we will see a mini refresh in the spring, but i doubt it will get the pro features. It might just be a refresh with bumped specs and maybe pencil support if i had to guess. But I would hope they adopted the new design in a mini pro.
Right now in 50/50 on buying one of the new pro's announced today. I will see them in person and go from there. If I do decide to buy one and I like the mini more, Ill just sell it off and buy the new mini when that time comes 😛
