what you say makes sense on paper but I think MArvel has a bit of a disconnect with their costumers and what they want. Also they probably did a lower print run on UXF and Annihilation because they've seen the poor sales of other omnibuses or seen that lots of them are still in stock but probably didn't really consider it that those books had really high print runs.
I honestly think it's just a bunch of businessmen looking at numbers and making decisions without looking up the reasons behind those numbers.
Just grabbed the complete Civil War 7 vol OHC set, Spidey included, for $320. I think I now have all my must have OOP Marvel books.
I brew the beer you drink. What's your super power?
Aren't print runs also based largely off of preorders? When I preorder an omnibus from DCBS 6 months in advance of its release, I assume that's the reason. They look at preorder numbers and use previous sales figures from similar books to estimate what additional percentage needs to be printed. This is just me guessing though--I mean, it makes sense to me anyway.
Amazon.ca currently has the long OOP Vol 2 of the Invincible Iron Man Stan Lee Omni listed as 'usually ships in 2-4 weeks" or something like that. Weird...
...actually 1-3 months..
