These just went up for pre-order and like the other Ghostbusters in the series, they look great.  Diamond Select does a pretty good job of putting out highly detailed figures for a good price.  The complete series is suppose to be 15 characters, each with a diorama piece to complete the massive rooftop scene.  With three in each series we can expect to see a couple more coming soon.

Slimer, Janine, and Quittin’ Time Ray make up Series 3. Each comes with bonus accessories in addition to their diorama piece. Janine includes a phone, alarm button, and take-out containers. Slimer comes with 2 alternate faces and a support stand that can plug into the rooftop. Quittin’ Time Ray includes a variety of interchangeable gloved and ungloved hands, as well as updated sculpting and paint details to reflect his appearance at the end of a long shift. Each 7-inch scale action figure features up to 16 points of articulation, and comes packaged in display-ready Select figure packaging. Collecting all 15 figures in the series (sold separately) allows fans to build the full rooftop temple scene from Ghostbusters!

If you missed out on series 1 and 2 they are currently in stock.  Series 1 features Ray Stantz, Winston Zeddemore and Louis Tully.

Series 2 brings you Dr. Peter Venkman, Dr. Egon Spengler, and Dana Barrett as Zuul!
