Less than 1 percent of websites have implemented Schema.org markup. However, pages with Schema.org integration rank better by an average of four positions compared to pages without Schema.org markup, according to recent findings by Searchmetrics.
It isn't clear to me what "schema.org markup" means--any semantic markup? Using Google's webmaster tools to implement that markup? Is the whole page marked up, or just a few key items, enough to form a snippet?
But, that more semantic markup is happening is what I am hearing in general; hearing that it is producing results is very good.
