Dark Souls II Shaky Cam Footage and Info Tidbits

It seems like quite a bit of information regarding Dark Souls II is coming out of San Diego Comic-Con, even if we aren't talking about stuff that's going to make for a sensationalist headline.

First of all, Redditor "Mkfshard" has some strictly mechanical tidbits (thanks GameRanx). Keep in mind that he/she played a pre-release build, so everything is subject to changes and tweaks at this point:
-Every action feels a bit more weighty. You're committing more to each movement.

-You're no longer invincible during any special animation, like opening doors or entering bonfires.

-Magic has been expanded! Each spell now has a weak and strong attack, and some are even chargeable! Two-handing catalysts also changes the spell somewhat.

-When you're targeting someone, you're no longer restricted to attacking directly at them. This kind of threw me off, as I tried to back up and then heavy attack, but then attacked backwards...

-Enemies are much smarter. Even normal hollows were rushing me when I tried to heal.

-The enemies the Mirror Knight summons are weak, easily killable with a single greatsword strong attack. But they distract away from the boss himself, which can get dangerous.

YouTube user SteamyPunkSouls has posted several videos (1, 2, 3 and 4, plus a little cameo from Solaire of Astora) of shaky cam footage of Dark Souls II, showcasing some of the levels we've already seen previewed since the first reveal and the boss fight with the Mirror Knight. (Spotted on NeoGAF)

Finally, YouTube user Barneezy Jones also has a video with some footage, which also includes some comments regarding the gameplay and how it's different from the original Dark Souls. Be sure to watch the video with annotations to turned on to get extra details on minor mechanics such as the ability to cancel out of opening a door.
