Unless it's a EU exclusive, it sounds like that site just used the word "trousers" to describe the regular PF.
People on this side of the pond don't use the word "trousers", so I'd assume that it wasn't a description coming from SS HQ.
I picked up a Robocop 3 w/ Jet Pack yesterday at a local comic shop.
I'm not a big Robocop fan, but like the design, and think that this is one of the best looking Hot Toys figures to date.
