I'd love it if they made this game. Along with the legendary case of the Bf-109 vs the Spitfire, the F-86 vs the MIG-15 is one of the closest matches in history in every aspect of flight, two a/c being the nemesis of each other.
10 years is probably about how long it's going to take them to come out with it. I'd love to have it when they do - I still think IL-2 Shturmovik is the best combat flight simulator around.
