Well since they already had full-size Play Arts Kai for Rufus, Vincent, and Yuffie it was only a matter of time before the rest of the VII cast started coming out. I think it's not a matter of if, but when.
That said, while I absolutely adore Play Arts Kai figures and I think they're some of the most flexible, posable designs on the market (with insane, excellent detail to boot), weird horseshit jobs like that Yuffie figure prevent me from buying them ever on a frequent basis besides as a collaborative birthday gift.
"Horseshit" job is harsh, I suppose - and almost every preview sculpt that's come out looks absolutely impeccable - but sometimes the manufacturers make the strangest decisions with the paint and production has churned out some very, very odd-looking figures. Skin tones have often been a common point of criticism (re: the "orange face") - the Street Fighter ones had the same problem, and on the Mass Effect ones some of the skin tones came out like someone had smeared dirt over the figure during the paint process.
In general, quality varies quite a bit (and plenty of anecdotes can be found of missing paint), especially for a poseable at the price points that Square Enix sell them at (though many figurines often have an asking price far above PAKs). Still, when the stars align on the QC aspect, the majority of purchases I've made have been nothing but excellent on all fronts.
At this point I'm wondering if we'll get to see a Cid and Barrett pre-Advent Children. The old designs were sort of tucked in the corner during the first 5 minutes of the movie. They've been reluctant to show them in full, and it's almost like they're "remake curiosities" locked away until the game actually gets made. Think of unanswerable questions like: is Bugenhagen part cyborg with a ball for legs, or is he just floating around on a ball? Would Dio get redesigned, or does he really manage the Gold Saucer in his underwear? Things like that. In cartoon form Cid and Barrett look acceptable, but what do they look like in a more realistic design?
So basically I'm wondering what they would change on the clothing to make them look more realistic and less manga (ex. Aerith's leather straps replacing the brass cuffs on her shoulders.) Would Barret still be wearing that uncomfortable looking tire rim around his waist, or would they simply change it to bandages?
In my headcanon the Ancients we see in the temple mostly consist of a spiritual form and that they linger in a state between life and death. In other words this black mage form represents their souls and magical alignment but is not what they looked like when fully alive. It makes sense also that black mages, masters of destructive magic, guard the Ultimate Destructive materia.
If the Holy materia had been guarded and the player had to find it, I think we would have seen white mage-type Cetran spirits.
My word. It appears that unicorns have crapped out a few of my rainbow-colored pipe dreams today. We finally have an ACC Barret, after all of these years of seeing the same lot of pretty boy character figures over and over. (Not that I mind pretty boy character figures, but still...) Now, if Square-Enix decides to churn out the mythically long-awaited Cid, then I'll gather some frogskins together and collect this series. Until then, I dare not give myself too much hope. A little. But not too much. Even Bandai never made a Cid... :\
