It seems like it is, given that in some screenshots it comes with three rows and in others with four.
I'm simply not a fan of hotbars in general and I wish the UI was closer to what we had in BG1-2 or in Solasta (cosmetic fluff aside they are conceptually the same thing: every thing in a fixed place -consistently- and few submenus for spells etc).
BUT
If we have to get one, at least a customizable version where you can chose how many rows there are seems like an improvement to me.
