Grigori Melnik has announced the plans for GAX 1.3 here, thanks to Tom for the heads up on this announcement. At last I can talk about something I've known for a while ;)
So really GAX 1.3 is the version to get GAT/GAX running in Orcas, but the team have taken the time to include a couple of extras, mainly they are Experimental hive support, VB template support, and a new GAX installer (using Wix)..... now I may be on my own here but I so don't get Wix, maybe I will in time
So that's it really hopefully this will be released out to the wide world soon so that I can start building some Orcas Software Factories
