If the browser were to prefetch search results, it would leak information to all the result pages about the user having done that search. (I once had a blog post accidentally rank on the first page for "XXX". I really don't want to know who is searching for that particular term.)
Google has to know what you're searching for to compute and show the results. So there are few additional privacy implications from the preload.
And your last case is exactly what will no longer happen. People will now copy-paste the original URL rather than the cache URL. Click on the link, and you're taken to the original site.
