It's kind of hard to tell which Very Rare will be the most expensive since we know very little about the Very Rares, but I would be surprised if Cad Bane is not the expensive VR of the set.

How about for uncommons. Any thoughts on whether there will be a pricy uncommon in this set?

How about R7? I don't think it will get to being like mouse droids, but I'm sure people will demand it.

The R7s are good, but not great. The 2 I get in my case will probably be more than enough for me.

UC run down:
BD Sergeant - (assuming the Roger Roger guy) some people may use more than one of these fellas. it will depend on the cost of the unit. If its under 8 or so, expect 2-4 in a droid squad. if higher 1-2, so could get into the midrange for prices but not too much higher.
Super B3 BD - depends on the stats and cost. if its just a jacked up SBD, not a high want for most people. But if it has .. hmm, double and GMA for 15 points... high want! I don't expect much from these guys, so assume that the cost will remain low.
Commando Droid Capt - seeing his stats, I'll be happy with 2 of them, most people don't use redundant commanders so his price may be the lowest of them all.
A4-Series Lab Droid - haven't seen the stats yet for this guy. he could be interesting. I'd expect his UC price to be midrange.
IG-100 Magna Droid - reprint. low price.
IG-100 Magna Droid Artillerist - grenades? Missiles? Range with Splash, either way these guys could become the new gungan artillerists. If the SA rocks (say missiles 30 for 10 points) and the cost is right, price can be high. not expecting anything too ground breaking (ala Death Star Gunner) so assume low cost.
LR-57 Combat Droid - Seen him, I feel his cost is too high to justify having a swarm of them, can get a Lnacer in there for practically the same cost. I'll be happy with 2. Mid priced.
CT Sarge - reprint. an older piece, but new Cody does nearly the same as him. low cost
CT with Repeating Blaster - cool mini, lots of potential with CEs, expect mid to high costs.
Elite Senate Guard - stats unkown. the last senate guard from Rots kinda sucked... so not expecting much (something like Elite Sith Trooper) mid costed more likely, cause at least they still look cool.
R7 - non-unique override, 7 points at the cheapest with Rapport, as said before. Mid cost, even though they are very useful, not expecting to see more than 1-2 in most squads.
Treadwell Droid - funky guy, some nice SAs and not too expensive to bring in. viable SS nerfer for all faction, can be brought in as reserves or reinforcements. Might replace R4s in squads, but cost is a littel more. we'll see. mid to low costs (think RA-7 protocol droid).

defiantly think with the animated show being out, all the buzz and hype and being a new piece i agree and really think that cad bane is gonna be the most expensive piece than probably asajj

I can see that just 2 R7's will be plenty for a lot of people, and some people will even get 4 by default since a lot of people buy 2 booster cases per set. I personally wouldn't mind having 3. I probably won't end up getting more than 3, but I do think there will be a good chunk of people willing to get more than 2.

In terms of pricing, I'm guessing the demand on this one will be comparable to the Twi'lek Black Sun Vigo, putting it at about $1.50 to $2.00.

I might be wrong, but I could imagine mouse droids, ug demos, and bacta tanks going up in demand due to their ability to get granades and heal 10 through the Rodain Trader. Whether, the Rodian trader will be a very good use of 10 point in a squad is debatable and it goes either way depending on the squad, but I would say more often than not, the Rodian Trader will be over used for a while anyway causing people to try and get their hands on the 3 point minis and auto-healing bacta tanks.

They are a common. Not going to go for $5, no matter what.

Really? I thought they were UCs. Gonna have to pick me up some for cheap...

what about GGDAC and Throne? there alot tmroe then 23 dollars lachesis

To think that Cad Bane will be below $20 dollars is shocking. Because he is fringe and he offers what he does, I can see him becoming the Next GGDAC/Emperor on throne. I will be surprised if he does not go for less than $25 at most places within 3 weeks from the release date. After a month or two I figure he will break into $30+.

That's my opinion of his price based off of previous sets and the hype of the community about him.
