Not really... if Airwaves Yamaha & HM Plant go away BSB might be *really* competitive. There is a decent sized field.
As for AMA, most of its problems are self induced. The incompetent management just made it easier for the factories to withdraw support.
It depends on how well this hybrid Evo class takes off. If Superstock engines and ECUs, with Superbike chassis can be competitive with full Superbikes, at far reduced cost, then I think they'll become standard equipment in the next few years. Wasn't that what AMA Pro wanted with 2009's rule changes? And obviously from the other side, MotoGP seems increasingly likely to be encroaching upon the more prototypical end of the production series idea.
And BSB's problems go right down the field. AFAIK Hydrex Honda, the most impressive non-works outfit, are still unsure as to what and how they'll be running next year. With Stiggy's Superbike programme unlikely to survive the winter, their engine supply will have to be rethought. Rob Mac look like they're going ahead, but without a shitload of development and support, the Yamaha just isn't competitive -- it was the paying for this that did for the Airwaves team. MSS Kawasaki did the season without traction control, which gives an idea of their level of support and funding. Suzuki are falling back alarmingly outside of America (actually, if it wasn't for Mat Mladin, they'd have had an average season even in AMA), even with decent works support the Crescent team aren't really front-runners.
I guess what I'm saying, is that with a big national series like BSB, 'competitive' isn't just relative to the guys you race every week. You want them to be a match for the best squads in the world, at least on your own terms, at your own tracks. I do agree, though, that if you take GSE out of the picture, the title's anyone's. Which will be enough to get me down to Brands in April.
