I think I know what toy box sets are

Toy Box sets comes with two characters and a Background Hexagonal Power Disk
Leaked ones
Wreck it Ralph- might come with Ralph and Vannellope and the Fix It Felix background disc
Frozen- Comes with Anna and Elsa and the Frozen background power disk.
The Frozen And Wreck It Ralph backgrounds have been seen in trailers

What are "background" discs - do you mean textures discs?
If this is the case are you saying the fix it felix disc is the dome with the arcade screen in the sky? I thought that this came with the toy box already as seen in the toy box tutorial - creating a wreck-it ralph theme. Correct me if I'm wrong.

^It's a power disk, and yes I mean the texture and skydive disk. It's been shown to be a power disk. Only playsets don't have texture power disk.

^ hasn't its been shown as preloaded.There is no way they'd make you pay 6.99 more for a power disc.

^It's two power disk, and it's been shown in the power disk video

When they first leaked I thought they were like you said with power disc.

I think we may get loads of content related to that film etc I'm interested to see what they are.

^Yeah, like a whole bunch of items and set pieces
