Notes about YGOPRO Duel Storm:

It is true that the Owner of TDOANE (Seto Kaiba) is doing some of the Programming for Yugioh Duel Storm! Although this does not mean that Seto Kaiba will be using Duel Storm, or even Staff on it, as the Old Administrator of TDOANE had got the project Duel Storm kick in to get away from TDOANE and Kaiba, Meaning that Yes the Launcher will be entirely different, and the community itself, different and reputable.
