Basically when all console potential has dried up they will bring it to PC, if they so choose. It begins :)
If that is true then why buy consoles at all, just wait for the better PC version at cheaper prices.
Bringing console exclusives to PC means there's less selling point for the console. A PC gamer might still buy consoles for exclusives, but you stop having exclusives then PC gamers will be glad they don't have to buy your console.
That doesn't sound smart, might be good for a quick buck, but then the next exclusives wont sell as much as they could on the console, and you shouldn't want people buying on PC due to high levels of piracy and cheaper prices.
These practices will hurt console sales, just look at Microsoft, first putting their games on PC and now no exclusives for 2 years, I predict this will hurt their sales really bad.
Imagine if Halo, gears and Forza had never come to PC, can you imagine how many xbox ones they'd sold? Maybe double. How many people bought an xbox to play Halo? A lot, if halo was on PC from day 1, I bet xbox wouldn't even be a thing today.
