The point (I guess) is to complain and not pre-order so the record company gets the hint.
As for a plausible pricing point the only thing that the record company has to do when it comes to the final price is deciding on their profit margin. eg on Amazon right now

All of Dylan’s original studio and live albums are included--42 albums in all. Fourteen of these have been newly remastered for this set, and each is housed in mini-jacket packaging, perfectly replicating each original release. Also included in The Complete Album Collection, Vol. One is Side Tracks, a new two-disc set of songs from non-album singles, compilations and more. A deluxe 268-page booklet featuring new essays, original liner notes and detailed discographical information is also be included.
You still think that the 6 disc set is good value , really?
Just for fun I searched ER to see how many times I begged for this release in the annual--usually multi-annual--"What should the next bootleg series release be?" thread. I stopped counting pretty quick.
Most people who aren't Bob-aholics will be buying the 2 disc version. At about 50 Cents a song, decent value relative to similar releases imo.
As for myself--I'll get the 6 disc set at about $1.09 a song. Double the cost for something I've wanted for years to me is fine. So yes, I consider the 6 disc set to be a good value relative to how bad I want it, especially considering i would probably pay even more than that for it.
The price will be what the market decides. If its sales fall short of projections, prices will drop.
