Are the in-game secondary characters playable?

I was watching a video from E3 yesterday and as the person explaining and playing in the Toy Box went through the various menus, he hit on a menu with a bunch if secondary characters. What I could see were:
- Edna Mode
- Rick Dicker
- Rex
- Hamm
- Bo Peep
- Filmore
- Ramone
- Guido
- Luigi
- 2 pirate sidekicks (the one with the glass eye and his buddy)

When he clicked on Edna Mode, his character changed to Edna. Are these characters going to actually be playable? Seems odd that they would skip the opportunity to sell them as figures. It would also seem that you could change a non-Cars character into a Car and go into that Play Set (as an example).

If you have a link to the video, we would love to see it!!

Welcome! As you can see by my avatar, I'm a huge Rex fan. I can confirm that as of right now he's not playable. Following this logic, what you saw was the NPC menu. However, they could be added later.

only Characters with accompanying figures are playable
