He did but im pretty sure he didnt do that on purpose.  He immediately said right afterwards all Windows 10 devices.

And if Windows 10 can stream PC on XBox then we really might get PC games on Xbox as well.   Will have to wait to hear more on that though

i bet that pc to xbox is alittle more work so its probably not ready yet but i would think it would be on its way

Microsoft puts some games on PC and others they dont.  ori and the blind forest is on PC but its owned by Microsoft.  Fable 1 and 3 is on PC.  Viva Pinatas and Kameo was on PC as well. 

They did say Windows 10 is coming to Xbox. We'll just have to wait till GDC to see more

We will be hearing more on Windows 10 coming to Xbox One later this year so its a possibility at this point.  The question is, is that rumor of Steam coming to xbox true ;)  because if its an actual Windows 10 and not completely nerfed, there is a possibility Steam could make its way over with Windows 10 inclusion

yes, he said PC or tablet and not phones

Fable Legends also on PC with cross-play is great, it means PC or Xbox owners can play with more friends since not everyone owns an Xbox or PC and since this game is pretty much made to play with friends I'm not sure how someone couldn't like it. As long as it's not a competitive Halo multiplayer with controller against m+k players everything is fine. 

Too bad that I'm still not interested in this game but well, I think with some rl friends it could be fun (like pretty much every co-op games^^)

I would like to see a game like GTA using this possibility. 

He did go out of his way to mention Steam.

Many peoples that have playing fable legends have said its pure fun 

Yepp ;)  With Xbox App they might be able to add achievement unlocking to games you play on steam as well.  Maybe. 

Thanks. I don't play games on PC so I assumed every Fable game was just for the Xbox only.
