Man... This is just extremely sad.
I'd rather wait 1-2 more years and have them release this game only for consoles first, get tons of money for it then work on a separate build for PC that looked like it should be looking after they have the money and won't go bankrupt or whatever, steam would cover those costs as well.
Or the opposite, like Witcher 2, PC first, then tone down everything from there and build the console versions, it is tons of work but not such a huge fuss as making everything from scratch, toning down is easier in comparison.
The consoles are close enough to PC that making them all is cost effective, smarter, and works. Plenty of other games have done it, with the PC version looking amazing.
So...it's not like it's an either / or situation. The process CAN work.
