The Gruntz website has an update on the status of the rules as well as an Excel based army building tool.
From their website:
A quick update in the build up to Salute 2011. I finally have my points calculation working! It took 10+ solid hours in excel but I no longer have to do things manually. I had the method but not the automation which is now in place. It is still a little rough around the edges but will be ready to launch with v1 to aid army building.
