Deleting them from the physical file does not remove them - that is done
with the reorg.  So the physical file will be the same size.  However, you
might recover space if the system removes them from logical file access
paths.  I'm not sure if *that* happens or not. (Anyone know?)  

If it does occur, the amount of space you got back immediately would depend
on the # of files, size of the paths, and when they are maintained.  (I.e.
if you had a large logical only used at yearend and it was set up to update
the access path at the next use, you wouldn't see any size reduction on it
until then unless you forced it to rebuild earlier.)
