I understand the reasons, but it's a shame that Chromia doesn't have the combiner parts. Would have liked to have had a full team for Elita.

 

Fact is, as with Hun Gurr who I got a lot of flak for when comparing with Silverbolt, that they save time and money with reusing the same engineering.

 

silverbolt and hun gurr don't actually share any parts.

chromia has several parts that are identical to moonracer and novastar.
you can see the same with chromedome and blurr, who share the same thighs, titan master body, and gun.

 

Looking at all the Takara listings, I'm surprised that there isn't a listing for a Japanese release of the supposedly Walgreens exclusive Siege Ratchet.

 

Sigh I never said they share parts. Don't rehash my words. I said same design. You realize that sitting at a desk designing costs time and money? And testing with grey models.
Hun Gurr is by all definition a Silverbolt design. Basically it is a trim down on costs due to the knowledge that the design works.
Now another type of budget cut is sharing molds. And that is done with yes Chromedome family and Blurt family molds. But only on a few insignificant parts. Parts that won't degrade that fast. Or at least cause issues when transforming. Other than that I would not know of many budget cuts. Well the head masters themselves could be on seperate sprews that don't particular belong to a mold set.
And I suspect the handpieces to be seperate. Since Punch/Counterpunch has one.

 

Give it time. Given prior form Ratchet will be out in Hong Kong etc c August and Walgreens October. I'd expect to see Ratchet after that.

Wreck-Gar, this year's Walgreens exclusive which followed a similar worldwide release pattern, only comes out in Japan December 31st!
