Don't know if it's been mentioned or whether my eyes are just playing tricks on me, but on the 'My Profile' section of the Disney Infinity website, if you look at the 'Disney Originals' section there's 9 empty spaces that have only appeared recently. I remember when 2.0 was announced, the empty spaces were the same for the new characters too?
Sorry if I'm wrong, but I thought it was odd that they've only just appeared...
