On top of that, as I remember it, Swen/someone at Larian explained during PFH 8 that the Dark Urge was exclusive to a Custom Player Character. If the player does not select Dark Urge at character creation, there is no Dark Urge in the campaign.
If it turns out, once the game release, that players who didn't play as Dark Urge get to encounter them, and can recruit them to their party, I'll happily update my opinion.
Actually it is confirmed that he is in the game, just you probably cannot recruit him. I got the sense that since he is behind all the serial killing going on you could either confront/defeat him or avoid him or escape or whatever.
