We all want this, as well as direct support for MP4 files, or recording straight to MXF files.
Choose one format and support it.

While they're at it, I'd like to see an arbitrary 90 rotation. I would like to shoot more video in portrait mode.

Gints, I'm intrigued. How would you display "portrait mode" video?

in the media mode, we should be able to select a number of clips, and delete them all (the hvx200 allows this, and it's a great help). as far as i can tell, we're only able to delete all clips, or go one by one, which takes forever.

By turning your widescreen tv round by 90 degrees !!

Ahhhh, the old "Landscape and Portrait rotating mount trick!".

If you're shooting full-body subjects on greenscreen portrait takes advantage of the greater horizontal resolution available in a 16x9 image and you'll flip it in post. However, since you actually have to physically turn the camera sideways, and in doing so you turn the lcd at the same time, I'm not sure when you would need to flip the display except maybe for playback.
