i read it just the other day....gotta find the source. sounded like things were in concrete with E Boz and DiSalvo riding Superbike, Herrin riding Supersport, and B Boz riding FX. (remember...no superstock classes next year).
Herrin is the only one with an open contract into 08, the superbike and FX riders have not been named. However a name that was in the rumor mill was that Makoto Tamada could come to the US in 08 and CE III coming in 09
