It apparently sold a little over a million copies worldwide, which I suppose is pretty decent for the genre. WWE '12 went a little over two million.Supposedly it did. I believe they were even working on All Stars 2 until the new CEO of THQ took over.
I'm really surprised they just kind of wrote Johnny Ace off. I expected after a few weeks he would have some master plan where he tries to get back in power, but no, he just vanished. I suppose they will bring him back in some capacity one day, but I'm still surprised that we haven't seen him in so long.
