A recent attempt to estimate the number of impact craters
remaining to be found is:

Stewart, S. A., 2011, Estimates of yet-to-find impact crater
population on Earth. Journal of the Geological Society.
vol. 168, no. 1, pp. 1-14.
http://jgs.lyellcollection.org/content/168/1/1.abstract

He estimates that there are about 845 impact craters larger
than 1 km in diameter that have been preserved over the
Phanerozoic. Of these, he estimates that about 714 craters,
of which 228 craters are larger than 2.5 km, are yet to be found.

Yours,
