On a Google support page they state:
"New! schema.org lets you mark up a much wider range of item types on your pages, using a vocabulary that Google, Microsoft, and Yahoo! can all understand. Find out more. (Google still supports your existing rich snippets markup, though.)"
By using "still" in the above quote this makes it sound like Google plans to eventually drop the rich snippets markup in favor of Schema.org.
With Google, does using Schema's Structured Data markup for reviews still give you the benefit of Rich Snippets (the rating information in the SERPS)?
