Success of the Korean War arena would largely depend on what version of the Sabre is modeled. If it's either the F-86E or the F-86F, then you'll see nothing but Sabres flying around. However, if one of the earlier versions of the Sabre were modeled then you'd probably see the majority in the Mig 15, as the Mig 15 out performed the earlier Sabres.
