Sadly, I agree with you.
I'd be happy if it happened but the chances of Federer ending no1 are slim IMO. I'm not complaining though, whoever wins, both are deserving of the title.
I have to give props to Federer though(yet again), I didn't see him ending the year in the top two at the beginning of the year, but he's had one heck of a rollercoaster year. The guy's cementing his status as all time great every time he plays, it seems.
Respect.
