Very interesting points - but remember the Aussie Open when Novak beat Andy in about 5 hourse ina five setter then beat Nadal in 5 sets in about 6? Novak can do it against Rafa. If Andy faces Rafa he can beat him but needs to serve well. If he keeps giving Rafa his weak second serve he'll be in trouble. I think based on form Rafa will take the title but he's not a dead cert. My feeling is that the likely final will be Novak vs Rafa and it will go the full 5 sets.
