or maybe they are feeling like gigantic wankers and are gonna release it in a few months
what the forget rockstar pc WILL run this game the best
It's set to release Spring 2013.
Anyways, Rockstar never releases it on the PC the first day. They always port it from the console to the PC; this isn't new. Just be glad they're not Sony "exclusive" like they used to be. The older titles were always being released on Sony's consoles before they were ported to the Xbox, then the PC.

Also, this is a leaked test print.
