According to Rockstar Games cofounder Dan Houser, a PC version of the open-world game is "up for consideration," though that's all the company has said on the matter.
The petition says it is a "big shame" that GTAV is not announced for the PC, specifically calling out the modding community being a "huge part" of PC gaming. "Modded GTA is some of the most insanely fun times you can have," a line from the petition reads.
A since-removed Rockstar Leeds job advertisement sought a programmer to help bring the company's "latest titles" to PC. This would potentially include GTAV.
The PC iteration of Grand Theft Auto IV launched about eight months after the console versions shipped in April 2008.
