I will most probably get this on the release date just like I did with gt5. Despite the obvious shortcomings I've played gt5 more than any other racing game in the past 3 years and personally I just love it when you can jump into an online race without any practise and just get on with it.
Looking at that xbow vid my only concern at the moment is the lack of bonnet view. The cockpit view in gt5 was always unplayable for me because of the low fps, slow responsiveness of the car, random rubber neck movement and general lack of feedback about what the car was doing.
I really hope pd will bring back some of the classic gt tracks from earlier versions. Like, Special Stage R11, rome, seattle, apricot hill, red rock valley, midfield and el capitan.
