They've updated info about DVD3, with Suzaku on the cover. And what I know about is...I'll just copy what I posted in the Kallen thread:
The audio commentary for the 3rd dvd will be done by Fukuyama Jun, Koshimizu Ami, Teraoka Kenji (mecha design), and Toba Satoshi?? (I dunno know how to read this guy's name ^^)
As for other products:
There's the collector's item blue boards, and "Transcient Happiness Curry" featuring Rolo and Lelouch. Yes, curry named for Rolo and Lelouch. XD
Just check out the official website for images.
Other than that, there isn't much of a change in the character profiles and the correlative chart, to my knowledge.
It's probably back translated. Japanese -> Chinese -> Japanese
Most of the time, when you go that route, you lose the essence of the original text ^^
