As I've said before, given this (emphasis mine)

The TRANSFORMERS GENERATIONS DELUXE Assortment features Transformers characters and designs from throughout the history of the TRANSFORMERS brand.
and given

40+ figures in the Generations line in 2013
All of these 'missing' Deluxes are highly likely candidates to be packaged on a Generations card with a "movie trilogy" subline.

I'm expecting Generations 2013 to be the same as Universe 2.0. It's the line where Hasbro can sell any Transformer toy they want to that isn't a Transformers Prime toy.
