If I had a choice between werewolf and werebear, I would take the werewolf hands down. Why put in a werebear when there is already a werewolf? More people wanted werewolf than werebear.
As they say. No one promised anything. Todd Howard said that the gamejam only showed what his people done. If any of these things were going to be in future dlc's, he did not know. Some things were and some not. It was Todd's people having "play" time and a way for them to relax, and Todd shared. Now everyone thinks that just because a few things from the gamejam were put into dlc's, that everything will be.
I know that but they did come true in some way shape or form (well at least a lot of them did)
Dragon mounts: You can't control them but you can ride them
werebears: Sadly you can't play as them
spears: Or at least the Reikling spears which are used as arrows
Kill cams for magic and ranged: Yes we have those
Adoption: Hearthfire
Build your own home: Hearthfire, sadly no skeleton butler though
Goblins: Kinda, but they are reiklings
Waygate fast travel: Kinda in Dawnguard. Basically the Forgotten Vale does this
Epic new mounts: Kinda, remember that skeletal horse with the orange flames in the game jam video? Make his flames purple/blue and you get Arvak
Mounted combat: Yup, we have that
Kinect shouts: Yup, we have that as well
Lycanthropy perk tree: Yup, due to Dawnguard
Vampire feeding: Yup again
Vampire Lord: Yes we have that, we even have a perk tree for it.
Yeah, that looks like most of what was in the game jam video. For some reason I think Todd Howard liked the ideas.
This is kind of a pattern that I have been noticing as well as the codeminers finding data in updates.
