I question the truth in that article and whether they really use Razor already. It's barely out, so is MVC3 and I haven't noticed any changes that would suggest that they would have converted it all from MVC2 to MVC3. It's a major task.
They might have some Razor in there because it is backwards compatible but to have it all razor is a stretch.
