I've seen people say they don't need an x1 because all ms exclusives are on pc.
The same people then say they will never use the windows store.
Well something got to give.
Some exclusives may have gone to steam, but I don't see any reason to believe that MS exclusives will be going to steam, Or at least their halo's, gears, forza, etc
The statement is fairly accurate, in good time the whole xbox catalog will be on PC.
The part about never going to use the Windows Store is a pretty much faux outrage. It's certainly cheaper to use the windows store than to have to purchase a console for those games and run them at inferior quality.
The goal for both MS and Sony is to make profits off of licensing/distribution fees from software, it makes little to no difference to them what hardware you buy, except that hardware purchases lead to a larger potential profit base. Hardware is sold at likely 0 profit to a loss at this point in time (total customer value likely is much higher than any loss incurred by discounting their systems).
When you look at that context, PC is just another channel/vector for them to increase their marketshare, or at the very least minimize their losses to their competitors.
So when someone says, well all I need now is a PC and a PS4 (something to that effect) their hope is that because your PC is going to be more powerful than your console, their hope is that majority of your multi-platform purchases are on PC.
It doesn't matter if their store is not as effective as they want it to be, what matters is that they get people transitioned to W10 first, as no store exists for them to even sell their goods on for Windows 7. MS will continue to work on their Store as time goes on, it may actually be good enough to compete with Steam, but it won't be easy. Steam is not easily replicated (you would see way more entrants if not the case), and w10 store is much more expansive in the types of software it must sell on it.
Anyway, TLDR; PC gaming isn't ideal in terms of profitability for MS (they would obviously prefer you to own XB and buy games and subscription on it), but having less margins on software is better than no margins at all (which is what they are currently trying to hedge against)
