I don't find it surprising, Epic Mickey 2 had a huge staff and sold way less than the first game, even though it was released on four platforms. I'm actually pleased with this, people learned their lesson from the first Epic Mickey and didn't buy another mediocre game.
I only played the first Epic Mickey, but that was enough to know that the series wasn't for me. I really wanted to buy/play the 3DS installment, as I adore 2D platformers, but the ho-hum reviews didn't help push me to scoop it up.
As for the news of Junction Point's closure, the only way this saddens me is if it means Warren Spector can no longer pursue his dream of making a new Ducktales game.
I'm sure that he is, but I'd like to see him have the freedom to work on what he wants... and hey, Dues Ex was his baby.
Also, didn't mean for my comment to come across as anti-Disney. I just really don't want to see such an important gaming figure being stuck working on god damn Epic Mickey 3. I do, however, have to admit that I would have been curious about Duck Tales. heh.
