The ALMS GT2 field has basically been all Porsches with no competition. BMW and Lexus have both announced plans to enter the category via ALMS's new GT2S category (S stands for sedan). As I understand it, the cars will run head to head, but the GT2S cars will not be eligible for LeMans. With Porsche in LMP2 and others joining the fray, ALMS is looking real good for next year!
