I just noticed in one of the tutorial movies from disney, this guy puts on the wrong powerdisc (his don't have picture, just the chips probably)
And what does he get? A Wall-E themed sky dome: http://www.youtube.com/watch?v=lk-cq7GuaWw
With other words. At the least Wall-E textures and Skydome coming up in powerdisc wave 3, or we're going to get a Wall-e figure surprise with powerdiscs
