Yes, you should be able to buy D2:ED for PC, get FoV and then get the conversion patch when it is done. The patch release has to be made through the D2:ED publishers, though.

For the Xbox version there will not be a conversion patch due to size restrictions, but I assume there will still be a patch to give the updates and fixes made to D2:ED with FoV.
