I'm not too concerned for a couple of reasons. 1. There is usually a drop off in communications as they approach a release. it seems to happen every time. 2. If they are actually redoing how the game manages resources (models, sounds, fx, etc) that is a larger change then lets say adding wheels. It affects many things across many areas of the game. I don't know the details of their revision management software, but this might be one that breaks a lot of things in order to make it all better. But I will say I am a bit disappointed that there has not been any official announcement. Oh well.
