Tomorrow is essentially the last direct to draw in preorders and attention to the game in general. It's going to be something big, so I feel it can be either middle evolutions or the supposed paradox forms. I can't recall a generation where the middle starter evolutions weren't shown off beforehand; yet if there are forms similar to regional forms I can't see why they wouldn't show them. Think of the public hype when Alolan forms were shown off, and how huge of a success they continued two generations later.
