LAUNCHXL-F29H85X: SOM and Launchpad availability

Part Number: LAUNCHXL-F29H85X

We are using the F29, still in development.  We need a dev board.  The launchpads we have are silicon rev A.  Do you have any latest silicon on the launchpads.  How about the SOM's , what is availability and is it latest silicon. Thank you.
