Being the biggest Ghostbusters fan on staff (proof of it is in my review of the Mattel Peter Venkman figure), I was kicking myself for not being in person at SDCC this year to see all of Mattel's latest GB items. Moreso since a replica Ecto-1 was present at the booth, but also because there was a venerable river of slime's worth of new prototypes on display!

A horde of new 6" Matty Collector items peeked out, including a GB2 Winston with slime blower, a normal Egon Spengler in jumpsuit (to finally fulfill my wish of having an Egon figure which I missed at SDCC last year), Ray Stantz covered in marshmallow goo and a possessed Louis Tully figure. Mattel also rolled out their 8″ Real Ghostbusters Retro Action figures, which will be released in early 2011 and will be made available at Toys R’ Us and at online retailers like the Ghostbusters Fans Shop. The first wave of figures will be Peter Venkman, Egon Spengler, Ray Stantz and Winston Zeddemore.

The biggest news had to be the unveiling of the PKE Meter prop, which came as a welcome surprise to every fan. The PKE Meter will be out “holidays 2010″ and will be available through Matty Collector only (surprise, surprise) for $50-$60 and includes lights, sounds and moving wings. Speculation has exploded as to what else Mattel will surprise us with and if this is the start of many props down the line, including a proton pack!

Check out the gallery for more images and hit the jump for all the release dates! Thanks to Chris H. for the photos!
