According to France VFR, the texture definition is very high: 50cm (~20in) per pixel. According to the screenshots, there are also a lot of buildings, which helps the city of light shine in FSX and P3D. Unfortunately there are no night images yet which should be somewhat of a sight.
Update: you can view a review of the scenery here.
