Unfortunately the PC gaming market is shrinking. And no porting to all 3 platforms is NOT a no brainer. It's seriously hard to bridge the gap. Between PC and console! - no vram - slower drives - more access to the hw so more owness on the programmer to use the hardware to get decent performance. - limited control of what you can dowload display etc (3rd party approval) Still, a lot of companies are making the jump. Just because it's do or die.
