No new characters. The villains that were just released are not on there. My character stats are not carried forward.
It looks like the previous PC exclusive power discs are there (Enchanted Rose, Flubber, Mulan's Training Uniform). Interestingly, all the circular discs appear to be unlocked. On the hex disc side, there's a disc called Scrooge's Top Hat, which increases your blue sparks. The Tron Light Cycle and Light Jet discs are there too. I'll post more as I explore.
