^ Ah, I thought TheMinion9 was referring to a clip from the game. I didn't take the trailer clips as a tease for a play set. A lot of other clips were shown in that montage - Lion King, Finding Nemo, Up, Tangled, Fantasia, Wall-E ... They even showed Wreck-it Ralph and we know there won't be a play set for that.
However, it is interesting that the directors for Frozen were shown, so maybe there is something to it. But does that mean we can also expect either Tangled or Bolt? Or maybe even Lion King or Beauty & The Beast as the screenwriter for those movies was also featured?
