Personally, I would have loved it if they had actually gone ahead and done two waves of the new figures, starting around January of 2005, similar to how they did the initial waves.
WAVE THREE: JANUARY 2005
2 x Obi-Wan in Clone Armor
2 x Snow Bunny Padme
2 x Kit Fisto (Mon Calamari)
2 x Threepio and R2 (two pack, since R2 would likely be little more than a PVC)
WAVE FOUR: MARCH 2005
2 x ARC Trooper (one blue, one red)
2 x Anakin (Yavin IV Duel)
2 x General Grevious
2 x Luminara Unduli
And you could probably go even further. Off the top of my head, that would still leave Barriss Offee, Ki Adi Mundi, Shaak Ti, Darth Sidious, Chancellor Palpatine (seperate for the purposes of the list), Battle Droids, and Super Battle Droids among the more "active" characters on the series that could be made into figures. This doesn't even begin to take into account some of the vehicles that could be made. Unfortunately, since it's more of a "niche" line, this stuff will probably never come to pass and these last three original figures (plus the Clone repaints) will be all we'll ever get, but it's still fun to dream.
