"Our DLC plans for SvR 2011 will outdo our past efforts, good to see threads like this.
One of these days I am going to publish an article on just how much effort goes in to creating a single Superstar for the game, its INTENSE. Its not laziness or lack of effort that we don't have 5+ characters in a DLC pack, it has everything to do with the amount of work and animation involved.
I know our DLC plans, i'm confident they will be well received, just don't expect a mountain of additional characters. That is not realistic.
