starwax, I'm stealing your format. Lo siento mucho, mi amigo, but I'm too lazy to type it all out myself.

Unleashed -
Do I have any?: all but three (RH Vader, Yoda, Jango)
My opinion: Best thing out there right now IMO.
Doing well?: Very well.
Survival?: Until Hasbro decides to do Luke and Leia Unleashed coming out of Padme's womb
Jedi Force -
Do I have any?: Vader
My opinion: Vader is cool, as are the droids, but the humans look awful.
Doing well?: Vader and Yoda are, at least near me.
Survival?: The end of this year. The fact that they are repainting Luke and Anakin already doesn't bode well.
Force Battlers -
Do I have any?: Vader (see a trend here?)
My opinion: Waste of plastic
Doing well?: Not at all. Even Vader is starting to hang around.
Survival?: They'll be first to the clearance aisles come January.
Galactic Heroes -
Do I have any?: A few. The Bounty Hunters and Vader/Ben.
My opinion: They look great and tempt me daily.
Doing well?: Despite the glut of ROTS first wave at WM, they seem to be doing very well.
Survival?: As long as the regular line keeps going, I think the GH stuff will keep going.
Attacktix -
Do I have any?: No.
My opinion: Waste of time, plastic, and money. YMMV.
Doing well?: Not in my area, unless you consider occupying more shelf space per square inch and not moving any product since the product launch a success.
Survival?: I think the one OT expansion will be it, but might be my crankiness making that prediction.
Star Wars Miniatures -
Do I have any?: No.
My opinion: No real opinion. I've intentionally stayed away.
Doing well?: I wouldn't know, as I don't pay attention.
Survival?: Probably a long time, I would guess.
Titanium Series -
Do I have any?: Slave I (which can sit on its stand in the flying position; this makes my nerdiness go into overdrive)
My opinion: They look great, but I try to not look at them.
Doing well?: Moderately well. Certain ones sit for a long time, but others (Slave I, ISD) fly off the shelves fairly quickly.
Survival?: I'll give them one wave at mass retail before they go the way of the dodo and/or Force Battlers. Pity too, as they are nice items.
Micro Series -
Do I have any?: No.
My opinion: Waste of time and plastic.
Doing well?: I have yet to see them move.
Survival?: Clearance aisle by the time Target does their fall reset.
