i really doubt any of the stuff from the game jam will ever be part of the official game, whether as dlc or whatever else
maybe like 2 or 3 of those features max, but that's it
just to clarify for all the haters: they do this for EVERY GAME they make, and this is the first time we've heard about it. these features aren't getting released. this is just something they do for fun.
maybe one or two could end up in a DLC but that's it.
half of the things in the game jam don't even fit in with the rest of skyrim. they could have kept adding new features for the next 5 years, they had to call it quits sometime.
