Google will soon notice that the old query strings are no longer existed on your site after few round of crawls. G will eventually drop the old links off from the serp and replace it with the new links due to the duplication rule.

Life is not that easy in most cases. If an URL is not mentioned anymore, Google often does not remove it from the index, but instead makes the URL supplemental [webmasterworld.com] which is in this case worse than useless. The URL may still pop up for search queries which match the content from the old URL, but not from the new, if you ever change the content of that specific page.
Proper use of 301 redirects and robot meta tags can help to prevent this happening but are no life insurance.
