With 100 results per page (and clicking: "show duplicates" on the last page)
site:google.com ( about 2.830.000.000 results) max navigation page 7
site:google.nl ( about 5.160.000 results ) max navigation page 8
site:webmasterworld.com ( about 275.000 results) max navigation page 7
I think this was always like this, at lest it was for a very long time. The number of results are estimate. But if you try to page through results, I believe you cannot see more than few hundred of SERPs listing at the best.
