Two pictures have surfaced on Yahoo Japan showing what apprears to be the Bludgeon and Scourge figures in an English language Armada style packaging with the Robots in Disguise label. While the the packages are somewhat confusing, this is consisitant with the trend we've seen from recent Hasbro RiD releases like the Runination repaint sets.
This may settle some questions about weather the toys were being issued for the Armada or RiD series and if they will also be released in the USA. Note that these may be test shots or mocked-up images. Without offical word from Hasbro, we cannot confirm the authenticity of this information at this time.
