UPDATE: IDW has revealed the details of the new crossover in a press release:

Our story begins when an old adversary traps the Turtles in a ghost dimension, as old adversaries are wont to do. However, all hope is not lost for our Heroes in Half-Shell, as New York City's resident experts on all things spooky quickly answer the call. The dream writing team of Erik Burnham (Ghostbusters, Teenage Mutant Ninja Turtles Universe) and Tom Waltz (Teenage Mutant Ninja Turtles, editor for Ghostbusters) are back to tackle scripting duties and will be joined by lead Ghostbusters artist Dan Schoening, whose animated art style has come to define the look of the Ghostbusters comics. An array of multi-talented artists with Turtles credentials are also getting in on the mass hysteria including Pablo Tunica (Teenage Mutant Ninja Turtles Universe), Tadd Galusha (TMNT: Bebop & Rocksteady Destroy Everything), Mark Torres (Teenage Mutant Ninja Turtles), and C.P. Wilson III (Teenage Mutant Ninja Turtles/Ghostbusters).

The first issue hits stores on November 1.
