No idea if this is official. I wouldn't put it past Saban, as they could and should pull us through a loop since Samurai has been so paint by numbers to the Sentai so far, but I doubt they are going to do it. I would love for them to do it, not because of Mentor Ji, I hate that dude, but because if it is true, than it would mean the part about Deker becoming the White Tiger warrior is true. But, really, this comes down to waiting and seeing. The pictures do look authentic, but, then again, you can make anything look authentic with a good photo editing software these days.
