After RTW, we were invited to submit some questions to CA and they did reply to them for the most part. They also nailed most of the early questions in my "game mechanics questions for CA" thread in the Ludus Magna.

One or two things - notably the combat formula and the derivation of the unit stats - CA did not want to get into the mathematical details of with RTW whereas they had provided that information with STW/MTW. They said they wanted to protect their intellectual property. I was disappointed by that, but can understand it as TW "clones" are more of a possibility now than in the STW/MTW era. One edge TW still has over the Imperial Glories, Marks of Chaos etc is in some of the hardcore wargaming elements in its battle model - morale, flanking, formation, terrain, weapon effects, weather, etc. Other companies can do battles with pretty 3D graphics but they often lack the depth of TWs combat resolution.

With M2TW, both the Org and CA are working to build closer relations - CAs inviting Orgahs to various events is evidence of this. This kind of relation could include stuff like us submitting questions about game mechanics. However, they are probably swamped with immediate post-release activities. I'll post again when I have more to report.
