I
think we are close to the finish line on these - seems like WGP has a lot of irons in the fire and has had some trouble with reliable casters over the past months - hopefully sme of the folks they have recruited will stick with them through future projects to improve turnaround time?
As for future Trek, here's my humble suggestion: Let's finish off the core Trek characters: Uhura, McCoy, Spock, Chekov, Chapel with serious/neutral expressions (oh! and also would LOVE the salt-lovin' alien that was hinted at ages ago!). Then move on to TNG core characters while continuing to roll out some "supplemental" TOS heads: variants like smiling McCoy, bemused Spock (eyebrow raised), Mirror Spock, Mirror Sulu, Drunken Sulu; aliens like Kang, Kor, Trelaine, Romulan Commander (Male and Female), Andorian Ambassador, Telarite Ambassador; and supplemental characters like Sarek and Amanda, Harry Mudd, Marlena Moreau. Then move on to DS9 core characters while releasing variants/aliens/supplemental characters from TNG, i.e. Season6/7 Worf, beardless Riker, Cheerleader/bunhead Troi, Tasha Yar, Lore, Q, Lwaxana Troi, Sela, Locutus...and so on.
The thing I hope WGP can see is that while some other properties they are working on may be "hotter" than Trek right now, Trek has a very rich, expansive cast of characters that die hards (like myself) would kill to own in 1/6 scale. Plus there is a new Trek movie on the way (would also be fertile ground for new sculpts) that will drum up future excitement for the property.
Soooo, bring on Kirk, Rand, Sulu, Scotty and let's get things rolling again!
