They are phasing out the PS3, they are trying to encourage sales of its successor, hence why they are taking value from the PS3 and giving it to the PS4.

This is also the reason why it doesn't matter with 360. XB1 does not have the position to be allowing this, and possibly the only benefit MS sees from this is that they spend less on console exclusives, at the expense of decreasing the console's value, which ironically, is the entire point of securing exclusives for the system in the first place. When the XB2 is out, all of XB1s exclusives can go to the OUYA even, right now, it doesn't make sense from a console manufacturers perspective.

MS just didn't pay enough, to do this deliberatly would be asinine.

The issue is MS isn't really benefting from having games on Windows. This is evident by MS' attempt at Games for Windows Live.

MS is not porting games to Windows. They are allowing them to be published to Windows, probably because they did not pay for full exclusivity. Steam is the vendor not MS, they don't make royalties of off games on Windows in contrast to games on Xbox. The 360, had the multiplat advantage and was the dominant console in the US, the XB1 has neither of those things. It has to compete on exclusives, having them avaliable on PC lessens the value of the console.

Steam is cross-platform, it sure as hell isn't helping MS more than its really helping itself and PC Gaming was more on Windows alone before Steam; i.e Steam has caused gaming to proliferate on Linux and Mac as well.

Windows is not helping Xbox, more or less.

Exclusivity to Windows platform literally means nothing, most PC gamer will agree, that like saying my car exclusively uses energy to run.

GFW was a failure because it was a half ass effort. MS indeed benefits from having games on Windows, it encourages millions and millions of people to stick with Windows. You're downplaying how large the PC gaming community is.

And your overestimating how much, Windows benefits from it, Driver Compatibility alone,  dwarfs the impact of the games ported from xbox platforms alone.

Steam is cross platform, but the support for other platforms is abysmal compared to Windows. That discourages gamers from moving away from Windows.

Abymsal compared to non-existant is still a huge increase. The majority of games played on linux are done through WINE (a windows emulator for exe programs).  Compatibility alone discorages gamers from moving away from Windows, until Steam OS, no notable OS has been made for the main purpose of gaming, its just that Windows was the most popular, so it got the most developers, so it has the most games, and a lot of its games aren't compatible with mac/linux. That is discourgement enough.

Windows has little impact if any on Xbox, which is why MS allows ports on Windows.

Don't misunderstand me, I said Windows does not help Xbox, does not benifit Xbox, that does not mean it has no impact. MS does not benefit much at all by having games on Window, but it means that Xboxs are less necessary.

Exclusivity to Windows discourages gamers from moving away from Windows.

Exclusivity to Windows literally means nothing. MS does not need to pay a dev to be exclusive to Window, compatibility and marketshare alone will make a dev prioritzie the os at the expense of others.

Here's the situation. You're looking for a negative spin and I'll continue to respond by pointing out Windows ports has little impact on consoles. We can keep going in circles if you want.

We aren't going in circles, we are going in a straight line, and you are going backwards. There is no negative spin, but this cannot be construed as a positive for Xbox and a minor one for Windows, its a much greater postive for PC gamers and Steam. I'm unconcerned with whether or not you downplay the effect of PC because you do recognize there is an impact, and my claim is that the XB1 is not in the position for MS to be making Windows impact the XB1 Console, little or not.

It is a smart idea to bring games to other platforms at a "late" stage once sales die down. It will increases sales in the end. Microsoft will bring games for pc but not every single one of them. The ones that do will come at a later stage. Sometimes it takes more than a year or even 2 but other times it might be shorter. I dont see a problem with that as long as they dont bring every single exclusive to pc. 1st party games probably wont. 

it will be cheaper on steam and the graphic will blow the xbone away...  thats a realy problem for m$
