That's the new forums, yes and strange is about as kind of a word as I've seen used to describe them by most people. Right now it's mainly for the Fallout players as they got forced to move over there a few months ago. Quite the eyesore of a "forum" to say the least as the software behind it - Jive - seems entirely unsuited for use in an internet gaming forum. The forums for the Elder Scrolls games will move over there eventually, and many here including myself have no plans to move when they do.
The hope is that they wise up and keep these forums active or at least make some MASSIVE changes to the new forums. They've done nothing to this point to change things to any great degree, however despite extensive complaints and suggestions for improvements so it doesn't look good at this time. I don't see me wasting my time on that place if/when the move happens so it'll be time to say goodbye for me as well I suspect. Sad, as I've been here a long time but I doubt they care at this point.
As for the thread subject, as was said I don't see them adding any significant features such as a Survival mode and a lack of bug fixing I wouldn't put past them either. This remaster/rerelease or whatever you want to call it is mainly for consoles and getting modding support in place for them. It being the "laying the groundwork" stage for the return of paid modding for future Elder Scrolls and Fallout games wouldn't be all that great surprise either for that matter.
