Here's something I never thought we'd get to see - Ebay seller amoronline has listed an auction for the never-released Transformers Animated Activators Electromagnetic Soundwave
. Electromagnetic Soundwave was a white recolor of the original Activators Soundwave, previously revealed when his instructions surfaced on Hasbro's website. His deco appeared in the two part "Human Error" storyline.
Like many later Transformers Animated releases, Electromagnetic Soundwave never made it past a handful of test shots. To be honest I never expected to see what the final product was meant to be like - so getting to see this, even if we can never own it, is a nice surprise.
