Well, the people making the cels seem to have 
decided that the value is in the neighborhood of 
$180-$250 give or take a little. That's the price 
tag I see on most post-production cels for sale.

However, I'm someone who agrees with your notion 
of them being a bit like "mega-fancels". Yes, 
they're made under the direction of the studio, 
which is an important (and nice!) difference 
from "normal" fancels. But they're not hanken, 
and they're not production. . . To me it kind of 
seems like they're a lost inbetween, trying to 
fill in some kind of gap for fans -- and a gap 
that the studios themselves were never interested 
in before anyway. Post-production cels just seem 
to lack "purpose". (I think that's the word I'm 
looking for.)

I'm not carving in stone that I'll never ever buy 
one, but I'm definitely not running out to get 
any. I'm not even really interested enough to 
look at post-production cel updates. If anything 
from a CG show, I would rather have the original 
gengas. Something that was actually used.
