According to the blurb on Wizards website it's only going to include two classes, both of which I've never heard of before. Then again that could just be poor marketing.
Avenger and Invoker are the new, never-before-seen classes for D&D 4e. Bard, barbarian, druid and a few others are going to be included. Gnomes, half-orcs, etc. etc. will be in there for races.
Vin Diesel plays RPGs?
He's welcome at my shadowrun table any day. 


He was a D&Der and wrote an intro the D&D retrospective coffee table book that was released awhile ago. This may be apocryphal but I read somewhere that his D&D character name is tattooed on his person.
