Amazon DOTD (12/30/2015)-Rocky: The Undisputed Collection $17.99 (7-disc set)
 

Offer expires Wednesday, December 30, 2015 at 11:59pm (PT). I'm not familiar with the different versions, but here's the offer(s). Both versions feature all 7 Rocky movies on Blu-ray, but with no enhanced packaging:

A 7-disc set, dated Nov. 3, 2009 is $17.99.

A 6-disc set, dated Feb. 11, 2014 is 39.43.

The 2009 set has a bonus disc, titled Rocky Anthology Bonus Disc, which looks to be a standard DVD, and has these features:

Feeling Strong Now! Game

Three Rounds with Legendary Trainer Lou Duva
Interview with a Legend - Bert Sugar: Author/Commentator and Historian

Sorry I'm not more knowledgeable on the details, but I think the 2014 6-disc set has remastered transfers. Don't know if any of the bonuses were carried over.

I'm pretty sure the 6 disc contains all the extras you listed (not sure about the game that's listed). They're on the Rocky 1 disc which was the only disc remastered in the later set. It has been on sale lately recently for as low as $13.50 on Foxconnect and $14.99 on Bestbuy (it's $17.99 at BB now). I prefer it for the thinner packaging.

I'd almost get this but with the information about the re-released set containing a remaster of the first film and the fact that its been on sale lower I guess I'll wait.
