Hey Chrisby, Eric IS on the ice platform. Don't believe me, go to WIKIPEDIA.COM, please do, cuz they actually tell you about his return. Its not Dr. G aight. Who knows if he is even gonna be in the SAW movie, he may be in the very last one for all we know. And i THINK the guy in the chair is Det. Hoffman only cuz his hair and skin color are very similar. and lastly, if it was Dr. G on the ice (which it isn't) wouldnt he have a damn prosthetic foot instead of a footcast. Piece the puzzle together here: Eric is the one on the ice cuz he BROKE his foot in SAW III and is wearing a CAST. Make sense, cool?
