I haven't noticed any rich snippets on Bing or Yahoo! from using HTML5 or microdata, but I don't remember ever seeing many rich snippets on Bing for searches and Bing is my default SE for personal searches -- As far as Yahoo! goes, what is Yahoo! besides an e-mail service again? lol
To me though, using correct semantics is about way more than "do I or don't I get rich snippets" -- They can be a nice "bonus", but they're not the main reason I use the structure and markup I do.
