WOW!  I swear I didn't have ANY knowledge that Hasbro was planning this when I did my version.  I know it's Shockwave here and not Megatron - but that's eerie!!!!

Hasbro's is 
much cooler with the actual Shockwave gun-barrell mold and the Mini-Soundwave & cassettes are awesome, but that's spooky - they even put the stickers where I did (basically) & went with Destro to man it too.  Too bad this is only a SDCC exclusive - probably go for $300 on ebay.  
Great Scoop 218!
