Have started seeing new Google results come through this morning.
Usual topsy-turvy (sp.?) update, i.e. sometimes new results sometimes old ones, so try a couple of times for different servers.

If I recall correctly, any new or changed pages that got spidered in Feb were appearing in search results about two weeks later. But your mileage may vary, as always... predicting a search engine's future behavior based on it's past habits is a risky business. :)
