A little slow on the posting of some of these Xbox One reveal trailers, but I’m a busy guy.  Anyway, this is definitely worth watching in HD–the particle effects and lighting in this game are incredible.  Microsoft has confirmed that this (and the Quantum Break trailer) are running on Xbox One dev kits; so, this is in-game footage.  It’s gorgeous.  Forza Motorsport 5 is an Xbox One launch title, so it will be available later this year.
