Funko showed of their Pop vinyl Ghostbusters figures, including Winston at New York Toy Fair. With eyes like theirs, Egon could have contact lenses for back up. I like the details with the equipment and as is the norm each Ghostbuster has their own equipment accessory.
You could be miffed that Winston appears just to have a Proton Pack. Since decision making people seem to think Winston is the default driver for ECTO-1, his “accessory” will be the ECTOMOBILE! Ectomobile? By the picture below and seeing Winston above you could draw the conclusion that any of the Ghostbusters can stand inside ECTO-1.
