They already had the whole team in that scale in 2010. They were the first figures they did in this scale. It seems they're re-releasing at least some of them with metallic paint. They're also doing the Megaforce rangers, too. For anyone looking to get Robo Knight, I'd suggest waiting for the metallic version. I'm honestly not sure why they decided to not make him all silver to begin with. The only reason he isn't is because they randomly decided to make his arms and calves gray instead of black.

I'm looking forward to that Lost Galaxy Red. I'm curious if they plan on releasing every past red ranger.

I hope they release all the MMPR team in 4" again and I hope they paint their weapons the right color this time as well. I'd also like to see more "Legacy" Rangers that have never been made in 4" start to make their way into the line. Something like having a wave with Overdrive Red, Mystic Force Green, RPM Yellow, etc, etc. Although I think something like that is more likely during Super Megaforce when kids might actually be seeing those Rangers again on their TV screens.

I knew of the 2010 releases, was just wondering if it was known how many of them were getting the metallic treatment this year. If he's not hard to find, I might get the 4" metallic MM White Ranger figure instead of the big 6" version. At that scale I would be tempted to get the whole team, even though I'm also going to have all of them in the form of the blind-bagged minifigures.

Edit: Looking through a Toy Fair gallery, there's a metallic MM Red Ranger on the way too (seen here alongside MM White and LG Red).

cancelled?
 

Seems that Putty Soldier and Alpha/Zordon may be cancelled? They've yet to be released.
Nothing yet for Lost Galaxy Red either.

Putty has been spotted in UK
 

Is there any difference with the putty figure compared to his original 2010 release?

Same as the 2010 release. Just include the (misspelled) trading card.
Below is the 2010 version. I ordered two of the Power Rangers 20 versions. Should have them in couple weeks from UK. I'll post update.
