At the moment, I'm more concerned with "what will we get in the collector 3.75" line" than I am with whether or not it will exist in the future.
Once the Sequel juggernaut starts, with the "one-off" side-story movies squeezed inbetween ep7/8/9, will there be room for OT 3.75" collector figures at retail? Or will the toy lines be so movie/tv focused from 2015 and beyond that the days of "obscure OT background alien" are over?

It's probably a pipe-dream at this point, but my best case scenario would be:
- a 5-POA 3.75" sequel/new movie line for kids filled with gimmicky movie figures for kids (and some collectors)
- a 6" line for collectors with 2 waves of movie-inspired 6" figs in the Summer/Fall and 2 waves of OT/PT figures in the Winter/Spring
- a "Star Wars Universe" style 3.75" collector line that can give us figures from all over the place - OT, Prequels, CW, EU, KOTOR/SWTOR, Rebels, Ep7/8/9, Stand-Alones, etc.
If Hasbro doesn't find a way to include OT/PT/EU figures in the 3.75" collector line going forward, then I guess I won't really be all that upset if it dies.
