I assume this only applies to VTLs? Once it's written to tape, how hell can you dedupe it?! You can only dedupe instances in the archived, vaulted media catalogs, the physical data stay on tape, unlike disk where it can obviously be removed at will.
Nope, you got it right #

The "deduplicated archive" functionality referred to in the articles refers only to object-level deduplication (ala CAS, SIS, etc.). It's not "true" dedupe.
Yes, NBU will continue to store data in its original format on tape. I would reword your statement slightly to say that it only applies to disk targets, not just VTLs.
AFAIK, only CommVault is storing deduplicated data on tape, but I haven't been particularly excited about that idea.
