The UT 4 gang is posting a weekly chat about that they are up to and answering some questions from UT gamers on YouTube. Very interesting stuff. It's great to hear them talk about maps and modding, even character modding, among other things. Particularly the notion of being dependent on the community for new ideas and output in that regard.
They've also been releasing early pre-alpha game play testing, etc.
Here's a link to one of their first chats on YouTube. It's about 45 minutes long.http://youtu.be/z8Nlz7XonCs
