Simple answer: No.

In short, my experience has always been that their order of preference 
is as follows:

1. Microformats
2. Microdata
3. RDFa (specifically GoodRelations).

Basically, GoodRelations is what's keeping RDFa on the list and on their 
strategic radars. Again, I comment from experience rather than speculation.
