It looks like the folks at Jazwares have released a new version of the Noob Saibot figure, this one more accurate to the costume worn in the game. As you can see from the photo below, which shows the two Noob figures side by side, there is much more contrast, with the parts of the figure that were originally gray much blacker, and the highlights on the chest much brighter.
This figure is already available in retail stores everywhere. A huge thanks to MK Online forum member of Fuzzd0rk's Mortal Kombat for the news as well as the photo!
