PC games have always been cheaper then console games even if they got the exact same features, so that post was just utterly useless and misleading.
Secondly they've stated that they won't be doing any work on the PC version. It's merely As Is, hence why it's also knocked down in price.
It has nothing to do with Piracy or Console/PC games. It's simply because they've said they won't be as on the PC as they will on the console.
Not to mention the PS4/Xbox (insert numbers here) are arriving soon so they'll probably just focus on that aswell and leave the other consoles behind.
