perhaps club tokyo just did an update talking about the new one (though the base on this looks black)...as far as I know the two green versions were the only ones made...
Marmit just posted March pre-orders, The Baruzasu is among them: http://www.marmit.co.jp/ Another stunning re-release is the giant Spectreman Bakular ant!
I just answered my own question by referring to my Quanto magazine (which has the VP summary list). The blue that Club Tokyo refers to is for the clear blue translucent released in 5/97.
Baruzasu is from episodes 41 & 42 of the Japanese tv series AMBASSADOR MAGMA (Magma Taishi) known in the states as The Space Giants. There is a very nice write-up on Sci-Fi Japan.
