Update From Konami on 7 November 2007

Here’s some of what I found.

Two new duel disk; presumably parts for the upcoming winter championship:

A Duel Disk which was presented to all CHAMPIONSHIP Participants.
Finally, the perfect Duel Disk for the students of Ra Yellow.

Battle City Yellow

Comes in a finish fit for any Egyptian God. Certainly makes you look the part!

New Gunslinger cards

Also it looks like some animations were added for when Obelisk and Slifer are played (not that they are enabled in game yet). Shame I havent perfected how to convert the text scripts that create the shockwave animations entirely yet …
