Well in that case I dont know, all any of us here can do is speculate. Well, most of us anyway.
Personally though I would think that the most likely result would be to seeing AF Corse in the FIA GT Championship again next year and perhaps with a car or 2 at Le Mans. Going into the LMS would be a backward step, if you look at the quality of GT1 and GT2 teams in the LMS compared to the quality in FIA GT I think you will find that the FIA GT Championship is of a higher calibre.
