Well,if it happens then i clearly don't think the outcome would be the same!
Tsonga seems to own the Djoker mentally since their last match in AO.
All i have to say is that if by any chance Tsonga makes his second AO final in a row then good luck to his opponent in final,be it Federer or anyone else!
He would certainly be fired up after his last year loss there.
A Tsonga-Federer would be great in some sense: Federer trying to equal Sampras's record in Slams against the current active player whose game looks like the most to Sampras.
