If you want to be more accurate he's a remold of Shin Zangetsu. There both repaints/remolds though. In fact most of the Arms Change line is jus slight remolds of the Baron and Gaim base suits.

Your article states that the pre-order page showed that another ACPB two pack was going to be revealed. This is wrong as the image was stating that the transformation for Mars and Kamuro will be revealed on July 22 which is after the movie is released in Japanese theaters. It's a mistake and we all make them, but I just wanted to let you know. For now it seems that the AC doesn't have any future releases planned due to the lack of a teaser on the official product page on the Gaim site: http://www.b-boys.jp/gaim/products/ac_pb05/

True, but most AC figures at least have a unique headsculpt... Kamuro just has Gaim's with a different crest.

I much prefer Mars in "real life" but the execution of the toy looks really clunky and awkward, definitely think Kamuro has made it better to toy form even if I'm fully aware it's just a repaint of other ACs and engineered just like Mars is.

These are gorgeous! I still wish Kamuro was a green apple, like it should be, but as is I'll take it. I mean the blue is nice, just not for an apple.
