No, we don't. We really, really don't. Hilibrand works well as a self contained set of quests that have no major impact upon the rest of the game. The tone and mood isn't like anything else in the game - nor is it to everybody's tastes given how over the top it is.

It would also risk becoming very stale given how repetitive his antics tend to be. I'm hoping that we get to see him every 2 - 3 patches instead of seeing major resources devoted to dragging out his story even further.
