I'm gonna go out on a limb, because I've been fairly bored to tears with this entire edition of the TdF. I say the combined attacks of VdB, Nibali, Evans (who is showing he really doesn't have much left in the tank), and maybe a surprise guy or two, will finally crack Wiggins, and Froome will go up the road (as he said he will). However, I think he will sit on whatever group is out front, and if Wiggins can't climb back up, it will come down to a small group at the end containing Froome. The obvious choice for the win is Nibali, so I'll say he will shed guys on the final descent.
