Voice-overs are being added to existing (linked above) and presumably future videos on niconico douga. These are basically the comic in animated format (there are small differences, though).
During the Christmas eve broadcast there was a sneak peek of some of the voiced video. Also, Porurin-sensei and the seiyuu chatted about other future possibilities (e.g. character songs, drama CD, etc) although it was more random banter and brainstorming than a serious discussion.

Or "gap", as in "gap moe"; presumably, the contradiction of voice overs on animated comics.Kou-chan will be voiced by Ms. Yuzuki Miho.
