Considering as little help as VdV has had in the past, I tend to think he won't. Vaughters is going for stage wins without a true GC threat. Hesjedal is a little like a poor man's Mick Rogers at this point. He's going to have to do it all himself because he really doesn't have the team to support a rider (no pun intended) with serious GC ambitions without Vande Velde.
With the question marks around VdV's health coming into the tour, Hesjedal was really the only rider seriously capable of helping Christian in the mountains. Now, Ryder is all they have with Zabriskie nursing injuries and unable to stay near the front. Millar can't climb well enough to be there when it matters. Van Summeran is decent, but he's more suited to the classics and not going to be there to pull his GC man back on the last climb.
