I don't understand the promotional poster. It raises more questions than it answers. Why are the Saiyans fighting some Pharaoh feline? Why does Gohan transform into Super Saiyan if he already was in an elevated state? It appears to occur after the Buu Saga but prior to the final World Tournament.
The animations definitely look slick. This is a modern DBZ and the creators want to emphasize it. I'm definitely seeing it spring 2013 if only to rekindle the joys of my childhood.
