it will happen after the AO. Ferrer will be at worst number 4 (he can be number 3 if he reaches AO final and Murray doesn't reach QF) unless Berdych wins the Australian open and Chennai and Ferrer loses before QF, or Berdych wins the Australian open only and Ferrer loses before R16.
Well, of course. How did I get confused there? It is exactly 52 weeks.
Ferrer really should be #4 at the FO now.
For RG seeding, Nadal has only 2090 points, whereas Ferrer has about 4740(I think).
If Ferrer reaches a QF and nothing more in AO,IW,Miami, Madrid, Rome,Acapulco and Valencia, he will be at 5840(which is clearly a very low estimate). If Nadal does a clean swep of the clay season(3 TMS, 1 500) and nothing in HC, it will still not be enough to reach even this low estimate.
So, I would say Nadal being outside the top#4 for RG is pretty much a given now. And unless Ferrer or Del Potro surprise us all, Ferrer will the seeded #4(at minimum) for RG.
If Nadal gets drawn in Ferrers quarter for RG, there would be more screaming of fixed draws than MTF has ever seen before. If not, we will have the most interesting GS QF(on paper) of the past decade(if not more).
