I doubt this is true. Mike Mayberry (Intel) softly announced buried power rail last year, as a 'within 5 years' tech. That suggests it has been prototyped, since from final tests to HVM is at least 2 years. Maybe not great. Within 10 means an idea with simulation. Within 5 means prototyped. Interesting means never. Or that, at least, is my decoder ring.
