this is just a marketing gag. They want you to talk about them, be mad at them, etc. Then they will of course still release on PC and it will get attention once again. Honestly, it's not the dumbest marketing strategy. Better than what most indies do, which is pretty much nothing. At least this stuff is memorable.How to make sure your models get ripped 100%. Spite people.
Also big "due to high demand we've decided to make a PC version after all" energy down the road.
It's bait like Nabs said.
