I agree that there are alot of variables, the biggest being that a film 
recorder must
actually be able to resolve what it claims. Assuming it does, it seems fairly 
clear to
me that if I:

1. have an original slide
2. scan the original slide
3. output the scan file back to slide film
4. compare the two slides

The pixel density point at which you can't really tell the diffs between the 
two slides is
certainly getting in the *neighborhood* of true film resolution as translated 
into pixels.

Not claiming it's "scientific", but methinks that it shows that an honest 12MP 
of data is
about what Ektachrome 100 can resolve. Or allow for some error, maybe up to 
15MP.
But point is, you can SEE what you're comparing. Tells moi that any claims of 
some
absurd numbers like 50-100MP are very much off the wall.
