I agree with that statement :eyebrow

dat gold!

Are the heads articulated on the Ranger Keys, or does Gold's head have a misplaced tampograph?

Most likely misplaced. Otherwise BoA engineered Figuarts-level head tilting into a Ranger Key, given the general direction the 王 appears to be looking.

Some definitely made the transition to teeny tiny and chubby better then others.

Shadow Ranger looks decent, but the Time Force, Lost Galaxy and RPM Rangers look terrible.

EDIT: Scratch that, paying more attention to all the photos, they all look awful. Even if the spring-loading is good, I doubt I'll bother with these considering just how much bigger and better the Gokaiger ones were. I might just pick up a few if the "Legendary Morpher" screams stuff like "MIIIIIIIGHTY MORPHIN'!!" and "ZEEEEEEEEEEO!!", but I somehow doubt it will.

Definitely will be picking my favourite teams up, so all the Zeo keys are a must.

Really interested in seeing the apparent spring loaded gimmick in action and, most importantly, how these guys are going to be released.

Dairanger keys? Now, Sabans really got me thinking they will use the suits now.

That blue head after those Alien Rangers in the beginning of the gallery... Is that Ninjor? That's kinda cool, since Japan never got a Ninjaman key.

I'm pretty sure that's Ginga/LG Blue.

Seems like the key parts are all the same. It might just be that these are show prototypes, but I'm not hopeful for specific team names, let alone individual sounds.
