I am with Collin here. It is really a question without an answer. I mean
- it just depends. If you have a drum scanner nearby with highly trained
operator, then you can produce amazing amount of information and
tremendous enlargements from your 6x7 negative. For the references,
several years ago to scan one 35 mm frame on a drum scanner in Tel Aviv
was USD 25. And they clearly indicated that they will not assume any
responsibility if the film gets damaged in the process. OTOH, if you
have 16 MP K-5 and all these fancy tools (fractal upressing, etc), you
can probably get very far as well. Finally, it would also depend on a
specific picture.

There is no "fair" resolution comparison because the systems are so
different. There is chemical information on a larger negative wich
cannot be duplicated on digital because it is simply not present.
Likewise, digital information takes to enlargement much better than
does film (in most instances).
A 12MP dslr, APS-C size, will be about 3K DPI. Scan a 6x7cm neg @
3Kdpi and you will have more information available than there is from
the DSLR. Likewise, place the digital information on film via a film
recorder and you will have a lower grade image.
IOW, while the large film neg has better/more information it is more
difficult to manage for enlargement. Now, if you would shoot 8x10 or
11x14 and do a contact print -- then you would be tempted forget
digital.
There is a reason why a number of pros will shoot reversal and then
drum scan for digital manipulation. It makes sense.
