Where's the MSP432 going?

The recent deal on the MSP432 Launchpad had got me thinking. It's been out a while now. There's still only the two devices - differing only by memory size. The silicon is still listed as XMS - i.e. experimental. I'd have expected more to have happened with the MSP432 concept by now.

Is the sale because the final production devices will be shipping and they want to clear out the beta stock? Are more devices / boards coming? Or is it all fizzling out?
