I was pretty intrigued by the possibilities here; but with the hints of this being an all droid set, my expectations have pretty much dropped to zero. If it ends up being 6 astromechs, then that's just Hasbro rubbing salt in the wound for those fans who are still carrying the torch for the SA line.
I guess a couple of the newer droid designs from TFA would be cool to see in action figure form and maybe the 6th figure is a C-3PO using the BAF body that everyone was asking for several years back (but with a red arm to drive everyone crazy). However, just like Hasbro overdoing it with trooper variations and Rebel pilots, I've been droided-out for a while now.
However, if Grummgar was announced as one of the figures, then I would be ready to order this set based on that alone.
