Not the only reason. The performance of the AGP bus is also a limiting factor.
Unless an AGP-16x standard came around the current crop is pretty much as fast as they can get.
And also remember that the card manufacturers often also make mobos. Unless more PCI-E cards hit the market in lue of AGP cards, the uptake of PCI-E (which has been kinda slow because of the higher cost) won't really happen for a while yet.
