Since Pentax have already recycled the old film KX name for the digital K-x, I think it would be fitting for the next flagship (after the K-7/K-7s) for Pentax to be bold and recycle the estemed LX name, and call their new APS-C flagship the L-x. K-8 sounds too boring.
You could see in the styling of the K-7 they were reaching back to the LX anyhow, especially around the pentaprism.
One of my regrets is never managing to own a LX body. I have a MX, but no LX. If there was a digital L-x, I'd buy it just for that reason alone.
