I've seen plenty of changes, most notably in one of my sites that previously ranked number 1 for the singular 2-word phrase before Florida, got knocked clear to Siberia, appeared number 1 for the plural phrase (after never appearing for the plural before), and has now returned to the number 2 spot for the singular phrase.
The description and cache may take time to update, a lot depends on how quickly they re-spider your site. If the others are being exiled your site may improve its ranking without being updated or vice versa.
I am aware of a site that had one spelling error of a keyword on a page. The page was corrected many months ago, but it still shows up in searches for the misspelled keyword, and the snippet still shows the old content to match it. How long before this is corrected?
