I sincerely hope that this new version of the game re-implements the original armour textures for Witcher gear that the game once had.
For those who don't know or don't remember, Witcher armour textures used to have a number of sweet little visual touches implying their age and wear and tear from Geralt's adventures, such as flaking paint or scratches. When Blood and Wine was released, these textures were all replaced (even for non-DLC owners) with simpler textures that had all those little touches removed. Presumably this was done to help facilitate the colour-dyeing in Blood and Wine.
The only way to revert these textures on PC is to mod them, while on console it's not possible to see them at all. It would be great to see them back.

I also echo some of the earlier comments that hope a new, well-thought-out and polished UI is coming too. This links from another Blood & Wine era overhaul which was less than successful, in that it wasted some of the map screen real estate, introduced some cumbersome button flow, and reorganised the inv into an ugly weird series of columns. Some columns of items would scroll down off the screen for days, beside other columns which will never carry more than a handful of items; for instance, you get one 3-width column each for your 6 bombs and your handful of Roach items, the same width you get for your 50-ish potions, so obviously that column stretches way off the bottom. Same goes for your countless alchemy items which get 4-wide column. It would be nice to see a layout with a bit more thought put in.
