I suspect the GC guys will wait until the last climb, and mostly observe how strong/weak everybody is, but I'd love somebody to have a go. There is hardly any flat in the last 30kms. Astana seems the obvious choice - perhaps a 1-2 attack? Judging by the cobbles stage Birdsong is a good bikehandler, how is he at descending? An aggressive strategy in the first stage could catch other teams off guard. Trim the field on the first climb, attack on the second. It's unlikely, but other teams lost some decent climbers and if they feel good, then why not? I'm sure Vino would approve.
Most people here seem to think that Nibbles will lose few seconds in the uphill sprint, so why not try gaining few instead? Depends on the situation, I guess, if the descent is not technical enough and/or there's headwind he should stay tucked in and conserve energy. I think Nibbles still needs to be opportunistic and find some seconds somewhere because there are likely 1-3 better climbers (and TTists) than him among the contenders.
And, of course, given that I've now wasted 10mins writting this, they will do nothing today and wait for monday.
