My two cents. 

WARNING: Do not read if you are not in for a long 
rant and opinion coming for me!

I agree with the last poster. Even more so, in 
that, CG or Computer colorized (or whatever the 
terminology that anyone would prefer to 
use),compared to hand painted cels are less of a 
collectors item than ever before.It is so BORING!!

  Why I say this is because with CG, only 
sketches or layouts will be available (and dummy 
reproduction cels for us)  but, of course in most 
cases, they still will not measure up to original 
key cel or color hand painted cels, hankens 
(maybe), or artwork, artist recognized, 
production cels, etc. (IMO). 

Going beyond that narrow scope, hanken mono, 
original drawings,etc., will also actually 
appreciate due to the very nature of the original 
artistic talent of human beings original input 
and creativity vs. computer graphic (nerd) 
rendered by the number, mouse clickable",instant 
art. 

Cel art will indeed become more valuable on an 
artistic level as never before IMO. And even if 
it stays the same and ignores CG, all the 
better!! I like to think positive!

However, it is destiny perhaps that I envision 
both forms co-existing. CG drawings and concept 
sketches, as well as, present or then future 
past, hand painted anime cel art redentions. As 
well as hand painted, anime art coming from other 
countries, such as Korea. (I might be wrong)

If anime movies are pieced into CG with limited 
hand-painted art, than those hand painted items 
will be sought after. And their value wil rise.

Look at "Metropolice" as an example of CG vs. 
Handpainted cels. The hand-painted cels are 
expensive due to the lack of these cels, before 
they hit the mainstream market. The same could be 
said of Saiyuki (CG) rendered. If they had real 
production cels, many more fans of that series 
would be happy, instead of being offered sketches 
and reproductions-ONLY

A lot of the main character art from Metropoice 
is actually CG. I find that CG is unattractive 
and not very sought after. I don"t really see 
that changing, unless there are absolutely no 
more hand painted cels to be had! Even then I see 
collecting that CG art as mediocre at best.

 Nothing is original about –“anyone can use”- 
computer software, --anyone can do it art. PRESTO
 I feel very confident that handpainted anime 
cels will continue for many years to come to be 
important collectible, and joy for many.

I feel contrary actually, that CG will face the 
problem of not being valued enough. Even as I see 
CG making it's way. I hear no Ohhs or awes.. I 
hear,,"oh, yeah btw, that or this scene is CG" in 
a disconcerting tone. I see no big parade or 
cheer going up for CG at all. I see it's value as 
a negative influence rather than positive.

I think that the present collectors are the lucky 
ones. They are the one's that gain to benefit 
from the artificiality of computer colorization.
I suggest that you get all you can while the 
getting is good! I am. Okay rant over...

Thank you for your post.
Good luck,
