I think it's safe to assume nothing is or ever will be a limited edition from the Irrational store other than the signed runs. Honestly I'm ok with that as long as they are up-front about it, which they pretty much have been (with the GLARING exception of the Bronco screenprint).
Even those stupid little books were never officially called a limited release.

I think in the future I won't be in such a rush to buy, and I think I've had my fill of very expensive signatures. I still love Bioshock though, and I'm still glad we can get nice merch out of the franchise.
