That result in the Tour doesn't count for anything classics wise, Schleck and VdB were in the top10 that day too. This said, I believe that his 2nd place on Waregem and 10th on the Ronde are good indicators that he can have some cobbled potential.
If he can become a regular top10 on Ronde/Roubaix he can win one of them, specially Roubaix since luck plays such a big role.
About his talent on the hills, specially LBL type, I think it remains to be proven: it's not like TDU is a good indicator of that. Still, it's fair to say that he was impressive on Corkscrew.
I wouldn't be surprised to see him become wherever Sky wants him too: from cobbled classics rider to GT contender. If they could change Froome, Thomas has shown far more until now than Froome ever had.
