PvP would be cool... As an add-on. Maybe.
Don't get me wrong, I like to PvP sometimes, but there are much higher priorities atm, and knowing Larian they don't want to ship the game with an insipid PvP.
I remember playing Magicka, its PvE was fun and all, it had a great potential regarding PvP, but the arenas were just plain... Boring, to be polite.
I wouldn't want the same error to happen here.
The Steam Workshop is well integrated to most games supporting it, it's easy to use, you can install/remove mods in a clic. You don't have to spend hours on forums, searching for manuals as to how to install them, etc...
If PvP has to be integrated, it'll emanate from modders, and fun things can be done with only the vanilla game.
At first there won't be many mods of course (I'm myself really looking forward the editor but won't touch it without having beforehand done the game from top to bottom).
On the long-term we can expect a "Protect the Sheep", "Assault on the Abbey", "Release the Killer Rabbit !" game modes, don't worry
.
As for "modern console game fans", they usually stick to their console, if we're talking about the same pool of "players". They're not much into RPGs, and because there's a PvP feature in one of them, on a platform they're not used to play, will neither change the very nature of the game nor mean it'll interest them enough to buy it (especially if it only represents a side aspect of the game).
To sum it up, I don't think it'd be a loss not to include a PvP mode.
It won't attract the aficionados of PvP because they have other games to satisfy themselves ; it'll slow Larian ; it'll be more of a "last-second content" than something planned from the beginning which would naturally integrate itself in the game ; the editor will, hopefully, allow us to design our own PvP content.
