DW3110 release date?

I am currently designing my own hardware implementation of the DW1000 chip. However, I see that the new DWM3000 module uses a different IC called the DW3110 which is not available commercially.

What is the relationship between the DW3110 and the DW1000? Is it intended as a replacement or is it a standalone chip in terms of functionality, pin layout etc. ? (I see some improvements in power consumption and the addition of channel 9 support)

Is there a commercial release planned for the DW3110?

If so, will this chip be backwards compatible with my DW1000 design?
