It's the original masters, not the HD versions. The new extras are not being ported over. The only "new" thing here is going to be the slim packaging. In my opinion, this move is at least five years too late. Other shows which came out in expensive, clunky sets originally (X Files, Stargate, for example) have been out in slim packs for a long time. They all range between $39 and $49 right now on Amazon. This is a bad, bad move by CBS.
