I have seen the .mkv video... nice

, but why still using the old (slim) logo? Also, the video is divided in two parts, while one of them may have been enough.

(By the way, I don't know if the logo will change again for OA3).
No there isn't, and it's no big deal to me anyway since the OA3 reboot won't have any RoQ files at all.
Do you mean it will use a different video format, or that there will be no intro video? And why, to keep pk3 filesize small?
