Konami revealed some more information on their website…
Apparently the game is separated into five different Scenarios split between the Five Eras, and at current looks like it will be accommodating 3 different characters in each era?
KENN, the Japanese voice actor for Yuuki Juudai (Jaden Yuki to you more dub aware fans) will be returning to do new voice work.
However, don’t expect Yugi’s Japanese VA to show up, as apparently his contract with the talent agency Johnny and Associates prevents him from doing anything other than the TV shows and movies.
