Deadpool will NEVER EVER be on anything intended for kids. Anyone who disagrees either doesn't know Deadpool or doesn't realize how much trouble they would be in for putting an R-rated character on a children's product. Plus, the movie rights are held at Fox, and I bet Disney/Marvel have some sort of clause that would prohibit such an action.
I've called their Customer Support line before, and they had no plans at the time to extend licensed graphics to the L/XL size.
When you think about it, this makes sense. When compared to the S/M size and its target demographic, licensed graphics won't be very attractive to many older kids. By that point, I'm pretty sure the primary concerns are performance and discretion.
When you look at the upcoming designs, it seems that if anything they're going for more mature and subdued designs, relatively speaking.
If anything, the only designs I could possibly see coming to the L/XL size would be similar to the S/M ones, simply because there's already some kind of working relationship in place.
