Is TSM planning on adding data deduplication similar to avamar? I
understand how TSM does not duplicate data now but minor edits in files
or simple file name changes would result in additional copies of the
entire file using TSM today.

We recently had a pitch from EMC on avamar. I can think of some reasons
to pass on it (Having two separate backup/restore solutions is a big
one, cost etc) but some persuasive arguments were made supporting their
solution. If TSM is going to be adding similar functionality soon it may
be another reason to focus on other efforts.
