There's been no clue that it's Tonnika's that I recall... I think he was just adding to the fun of the thread.
Don't tease, especially on such iconic, if not X-files-esque mysterious, hold-outs of the line such as these two space hookers! That said, after pronouncing myself more than willing to drop $25 on Jocasta, considering she's one of the few minor (speaking) characters left to be made, I certainly have to be willing to stomach the same amount for 2 far more "important" OT characters remaining from one of our favorite scenes (especially from an action figure / diorama standpoint). I'd definitely be disgusted by the price again, but I'd still drop $50 x2 in a heartbeat for a couple pairs of these ladies that I never expected to see the light of plastic (that doesn't make sense, I know). Hell, if they never get made, I'll probably be dropping $75 - $100 on nice customs for each one just to fill the gaping Cantina holes anyway, much like I used to in the post-Kenner days of the vintage line (Sandtrooper, Tarkin, Slave Leia, etc). So even at a ridiculously lofty $50 a pop, I'll still be saving money.
I'd still prefer my aformentioned Disney astromechs though. I just wish EE would hurry up and at least divulge the licensee so we could could move on from all this (hopeful) figure speculation, if it winds up "just" being a Gentle Giant product instead.
Here's one more thought on the potential Tonnika Sisters: What if they came with the Cantina's
distillery section finally... That'd be a much easier $50 to stomach, eh?
