I thought this was one of the more interesting answers this week from SSG:
SSG: When it comes to prequel Senators, we haven't seen much lately. The most asked of them is the Senator Grebleips figure, the E.T. alien - will we ever be getting this figure, is it just unlikely because it's a background alien, or is it totally off-limits because it's an easter egg from another film? Also, what about seeing senate figures from Ep 1 like Edcel Bar Gane, Sei Taria, Toonbuck Toora and Mot-Not Rab?
Hasbro: Senator and Separatist figures have been very slow sellers for us, so while we're not ruling them out, they are not high on our list of figures to target. We're confident that we'll get around to more some day, especially if the collector base rebounds as these figures are 100% collector-targeted. Until then, they'll stay on the sidelines. Grebleips is off limits per Lucasfilm, joining (among a few others) the oft-asked for female Cantina denizens, Holiday Special live action figures, and Tyvokka as figures we cannot/will not pursue.
It sucks but i had heard we could not get the ET figure and the Holiday Special figures, and we knew about the Tonnika sisters but why Tyvokka. Whats the story with not being able to get a Wookie Jedi?
