This is from the same people that made the Lomac series but with a fully clickable cockpit unlike Lomac and Flamming Cliffs addon. I am not sure if it will be to the same fidelity and detail of LB2 which was brilliant. Graphics will be great of course as you can see from the video. As for system specs I think that if you had a current high end system such as a Core 2 Duo Intel 6600 or greater along with a Nvidia 7800GTX or Radeon equivalent you will be able to play pretty much without any fps slowdown except in very rare occassions. I know Sky that you are not a big fan of Lomac (being a big F4 fan), so I would just wait and see without getting your hopes up too much.
