DivineGamer;
I assume there was no UK 1.03 update because of limits MS places on the size and number of patches. Maybe if Larian released a patch then, they wouldn't have been able to release another significant update.
Unreal Warfare;
There will be a patch for the PC version of D2:ED to make it equivalent to DKS, minus the FoV section. However, the size and number of content changes made, etc, will make the patch too large for Xbox. Updating it to changes made in FoV should be possible, though (engine updates, fixes, but no changes to flying fortresses or enemy placement, etc).
