Third party group Planet X have posted prototype pictures
of their Project Genesis unofficial and unlicensed War for Cybertron Omega Supreme on Facebook. The prototype image shows the completed robot mode with LED feature in its chest. There's also a couple of size comparison images including one showing the thing grabbing the Hasbro Fall of Cybertron Bruticus combiner - this thing is going to be huge.
Please remember this is an unofficial item neither licensed or endorsed by Hasbro.
