I have my concerns about this. Origins was a huge disappointment, primarily because they tried to shove the entire plot of Red and Blue into four 20-minute episodes.
So what exactly are these shorts going to be about? From the implied battle between Blue and Lance, I'm gonna guess these are the events we the player characters didn't get to see. So I guess we're gonna see things like Giovanni taking over Silph Co.? The post puts emphasis on villains, so are we going to get in-depth stories about them? (also - where are Archie and Maxie?)
