I think Droid Factory would've been awesome as a line between now and the films, completely. I think even just repainting droids they have done would've been great filler... EU decoes or even just made up stuff to be neat and/or interesting looking.
That said, what they put out, how can anyone really complain? It actually comes to cheaper per-figure than otherwise... There are some "eh, another figure I don't need" kind of choices I guess in there, but at this point, this little set of figures was well worth picking up I think... not just for the droids, but I think in general it's just a decent round.
