I expect Fed to lose points. I doubt he's gonna defend his Rotterdam, Dubai, IW, Madrid and W titles. The only 2 events where he could gain a lot of points are Miami and M-C and he's not playing them. Murray won nothing last year until July, so he could gain a bit. Nadal is a huge question mark. I expect Djoko and Murray to become #1 and #2 at some point in 2013 and Nadal to pass Fed if his form is same as before, which is a big if of course.
ETA: the problem for Murray is the same as always: being more competitive on clay. Not sure if he'll ever manage that. Serve improvement is not gonna help him on that surface and I don't see much difference in terms of movement.
