I am a bit hesitant about the incorporation of Disney franchises into this game.
Mostly because I find Lego representations of existing characters a bit jarring to look at.
The Disney Infinity figures may be cartoony, but at least I can look at them and say, I know who that is.
When I attempt the same thing with standard Lego figures, I struggle to identify them.
The minidolls on the other hand, I find those more interesting/more visually distinctive.
But I am uncertain if they'll be able to use those in Lego Dimensions.
It would be unusual if they didn't though, since the Disney Princess minidolls already exist, all you'd have is attach them to a RFID base and make the ingame coding/assets.
If they didn't use the existing minidoll designs, that would mean they'd have to make all new standard minifigure designs to include them in this game.
