Holy shit! It's got to be Peter - it's just got to be, because God freakin' forbid that Doc Ock wear the original digs!
I think the biggest factors that this is Peter is because 1)The suit. I see no reason why Ock would suddenly switch from his "technologically superior" suit to the standard and 2)This was written before Superior, and I think re-writing Spideys dialogue into Ock might screw up the story.
