I'm not sure they will have. Perhaps a few of the really major companies like EA, but I know some pretty prominent developers for the platform and none of them have ever mentioned anything about getting priority tickets.
I think there's some subset reserved for Developer Relations and they give them out at will - I've never noticed a particular strategy with respect to app store placement.
However, that's a tricky road to go down. I have no idea what Apple's criteria is for that, and I know some teams that have worked closely with Apple in the past that never got that treatment.
