I was at a gun store earlier this month looking for one as well. The owner had been getting a few requests so while I was there he called Kimber. The story line:
Kimber has not been making the polymer frames - that has been done overseas (Israel, I believe). They have been difficulties trying to get the polymer receiver imported. Problems getting BATF approval. Some prototypes have been made, but nothing in quantity over here. Now Kimber is supposedly changing their strategy. They are going to buy the polymer manufacturing equipment themselves and make the polymer component here in the US. It is going to take time to purchase the equipment, install it, train employees, build an inventory, etc. The bottom line I got was we won't see them on the shelves this year and maybe not until the middle of next year.
We know they have at least made prototypes. At least one gun magazine has tested it and I could have sworn I saw a post from someone here saying that they saw one at a gun show.
I wasn't going to wait, I picked up an Eclipse Ultra instead.
