Currently ox-html has an option to replace links to .org files with 
links to exported .html files. I suppose, this option should be 
generalized to other export backends. It is up to user to set 
appropriate target format to get cross links between exported files.

For ox-latex usually there is no point to link .tex files, target format 
is almost certainly .pdf. However PDF files may be created from ODF or 
HTML files, so a user should be able to specify arbitrary suffix, e.g. 
".pdf", as a replacement of ".org" file links during export.

Besides "file:" links such feature should work at least for "id:" links.

There is another subthread to discuss link to .org source vs. link to 
target format.
