Todd kept his word on his biggest promise, we have seen nearly half of this stuff now.

He never promised any of it, and if I'm to be brutally honest, I think a lot of that stuff is downright stupid.
It's all gimmicky. It's there because it looks cool, sounds cool and gets attention, but when you actually utilize it, you get bored with it after 30 minutes and then you go do something else. Personally I would argue that crossbows are a more welcome addition than the vampire lord form, and as this thread clearly shows, the new armor types seem to be more welcome than the dragon mount.
Some of them would be welcome, don't get me wrong. The lore obviously cries for werebears, gimmicky or no, and spears would be another welcomed combat style. The others though?
Dragon mounts are gimmicky.
Adoption is gimmicky.
The vampire lord form, partly due to it's implementation, is gimmicky.
Personally I just wish they would pick a point of focus and....focus on it! Skyrim is desperately trying to be everything under the sun, and failing miserably at it. The Elder Scrolls has always gotten praise for having a large scope of things to do, yes, but they're taking this too far now. Things they implement need purpose, and sadly most of the stuff in that vid and in the DLCs so far? It's only purpose is roleplaying. Yes, it is a roleplaying game, but not everyone wants to roleplay a father and not everyone wants to roleplay a vampire lord. Those people walk away disappointed. In that sense, worrying about giving things a purpose and meaning instead. That's what Skyrim needs to learn to do.
