If that's the case... Should be interesting to see how much Titanfall flops on the PC. (I would be more than happy to be proven wrong however.)
Windows 8 is yet to command a decent amount of marketshare and PC gamers generally don't care for minor things like Xbox integration, GFWL was the proof of that. - It's already got all that working against it.

Now 50+ exclusives is a nice number, but they're still going up against Steam which has over 3,000 games with more being added daily.
It's like comparing the games library of the Virtual Boy against the Playstation 2 it's a laughable difference to say the least.

Then you have price, we PC gamers are cheapskates... we really are. - If they start demanding $100-$120 AUD a game like they do on console, they won't gain much traction.

Edit: It's not Windows 8 exclusive it seems, so this is really all moot.

Uh oh, interesting, but it doesn't show much :/

Ah, don't think that's going to happen. Way too expensive for the average consumer. You basically want a slightly less powerful xbox one built into tvs running windows 8. That is of no interest to tv manufacturers. They have a cheap board in there to run simple apps they have control over. Their main concern is keeping the price of the tv low, Licensing win 8, sticking half a pc in there and expensive Kinect tech will drive the price up several hundred dollars at least. TV manufacturers are also not in the business of selling at no profit or even at a slight loss.
MS can ofcourse try to launch their own XBox TV.

XBox live on PC will not draw extra pc gamers. They're not interested paying for a closed eco system when they can get more apps and functionality for free, and more games with mods for less. Publishers also rather avoid the closed ecosystem fee MS charges them.
And on the other side, is it really a good idea for MS to let their players experience the same games on PC, making the step to spend the rest of their time on Steam sales even easier. Instead of browsing the XBox games store after playing a 1st party title, a simple alt-tab will open up a whole world of much cheaper games.

Hmmmm. Interesting. That means Microsoft are opening Xbox Live up to Windows 7. As Titanfall can only be played with Xbox Live. As it is now built entirely around Xbox Live Cloud. PC and 360 as well as The One.

Good move for Microsoft.

 Steam doesnt have Cloud, and if Titanfall shows itself to be a game changer with Cloud then Xbox Live could have many titles not possible on Steam. Even 3rd parties like Respawn not just first parties.

You already replied to that message, you haven't replied to my other one about game counts.

However, I don't know why you keep bringing up the cloud and Xbox Live...
Titanfall isn't using Xbox Live on the PC, at all, it's using Origin.

Now the problem I see is you are putting Microsofts "Azure" in conjunction with "Xbox Live" and then thinking Xbox Live is somehow on the PC, that couldn't be farther from the truth, Azure is platform agnostic, you could run it on a Sega Dreamcast, it's not a service for the Xbox it's a service for the Xbox, PC, Windows Phone, basically *all* of Microsoft's products can use it. (Even stuff not owned by Microsoft, for example Sony could rent some rack space.)

Xbox Live is a platform, like Steam, Microsoft tried that and fell on it's face, it was called Games for Windows Live! And every sane PC gamer disliked it, I doubt they will relaunch it after they decided to shut down everything.

In the end though, the PC is so stupidly powerfull that cloud based computing isn't even required it's probably a couple of generations ahead of the Xbox One and Playstation 4 in terms of CPU performance thus it's just DRM in the end.

Do you even know what the "Cloud" is?

It's a collection of servers that handles processing tasks that is typically done on a host machine which is then streamed to the client.

If anything, Steam is actually superior to that of Xbox Live, the Steam network isn't controlled by any single entity.
Internet providers all around the world set-up Steam servers near their content delivery networks, which is an optimal approach as those servers will usually be in area's where the internet provider has high concentrations of customers.

Now the kicker to this is you get far lower latencies and higher bandwidth the internet provider gets to save lots of money as grabbing content right off their own networks is far cheaper than grabbing data of Akami which is what Microsoft uses to distribute data.

You can have as many servers in the world, but it ain't going to help if they're half a planet/continent away, games are actually fairly latency sensitive.

Now as for server based processing any company can set that up and make deals with internet providers to provide such capability, but it's a pretty pointless affair on the PC.

Did you read my post? My goodness.
Seriously, read it, in it's entirety and attempt to understand it.

There is absolutely no reason why it couldnt exist alongside the discbased version.

I know what cloud is. Respawn have said loads of times that no other company can provide for Cloud processing Worldwide except Microsoft. That is a fact.

It sounds like ur saying u want Microsoft to compete directly with Steam...they would get...wait for it...steam rolled.
