I'd have to agree. I think he can't wait to get to stud to not only breed his own but to lure the best commercial mares away froom competitors stallions, especially Coolmore's. I thought about this last night for a while, when asking myself why he would retire him because its certainly not about themoney. I concluded what you did.
Discreet Cat may or may not have a huge impact in the sire market, but Bernadini certainly will. Coming from the coveted Ap Indy sire line, and also posessing speed that many AP Indy's do not posess, its very safe to assume that he will be highly sought after and a good bet to succeed at the highest level.
