There is probably nothing really of value that I can share with you about that. It's been ages since I was involved, and I was more or less just a permanent resident in the freecraft irc channel. I haven't heard about any updates from Stratagus in forever. Some other games branched off the Stratagus engine, but I have never heard from them either, so they're not exactly breaking news.
I was pretty much gone when the name change to Statagus occured.
