According to VH1 Game Break there will be a Gears of War novel..
Heres what they said,
"Perhaps you know that one-time dean of gaming journalism Steven Kent moved on (and mostly out of game journalism) to write military-oriented science fiction novels about clones. He even was up for a Philip K. Dick Award for one of the books in the series.
"Now, it looks as though Kent has scored a prime video game novelization by snagging the Gears of War franchise. The novel doesn't even have a title yet, just "Gears of War 1." That number 1 at the end of the placeholder title indicates to me that Kent has scored a multiple book deal, maybe two, maybe three."
