That's correct. Also, you're limited on continuous drive speed anyways, because the flash won't recharge that quickly.

I'm not exactly sure what you're saying here. AF-C is always AF-C...it never changes. The camera may change AF-C to AF-S if you switch from, say, Dyanamic to Single Point AF-Area. But that's not something that happens in the middle of shooting, so it doesn't matter. Only AF-A changes in the middle of shooting, starting in AF-S and then switching to AF-C if necessary (but not when there's a flash mounted or the built-in flash is raise...at least on my D90.)
