implies that you can only manually focus in video mode. Is that true?
Yep, that was my experience with the engineering sample that Chris showed me. I ended up switching to Manual Focus mode while I tried out HD video mode. I hope it might not be a problem with the shipping iteration, but I wouldn't be surprised either way.
One of the things that would be neat would be a way to trigger the AF Assist light while you're in Manual Focus mode in dim light, but I didn't see that on the camera. There are lots of things we won't know until it's shipping.
