What tyre pressure are they running? Are they running the same tyres as they'll run in (e.g.) the TdF? The tyres didn't look any bigger than 700x23, but how do you maintain traction on that vicious surface with high pressure 700x23s? And if you're going to drop the pressure, especially given the nature of the surface, don't you need a bigger section?
Are the bikes the same as they use in pure road races, or do they use frames with springier forks and seatstays? Are there rules about this?

700x28 is the most common I believe, with lower pressure than normal (say 6 bar) and tubs to prevent pinch flats with the low pressure.

Hincapie used a prototype trek with a rear suspension but rigid forks. Aparently this takes teh edge off the cobbles.[1]

Am I correct in thinking that the green and black tyres a lot of them use in P-R and other cobbled classics are Vittoria Pave? If so, they are only available in 700x24 in clincher form -- I don't know if this is the case with the tubs they'll be using.
