Because Microsoft will allow remote-play from their Xbox One to all Windows 10 devices. 

Damn!!! Windows 10 is goingto be epic! No WP though which is kinda funny

So? It's not like it's a feature too many people are asking for. Most people prefer to just use their TV. And I don't think anyone will choose an Xbox over the PS4 because they're like "Oh shiat, I can totally play on my Windows Tablet with dat!"

If someone is really that much into the whole thing, he should have some extra bucks for a Vita. Has the best controls anyway, because who wants to carry around a Big ass controller for some gaming on the go?

In other words: Remote Play ain't no game changer.

Isn't remote play available in the majority of the Android devices that support it? iOS maybe soon enough.

Why would I want to stream a console game to my phone when I can just play it on the TV?

lol no they don't

No, They should just keep their focus on making PSNOW work on as many devices as possible.

Some SONY's phones and tablets actually do support remote play....

^^ also.. if you really wanted to, you could remote play off non SONY tablets and phones. For instance, I can remote play my ps4 off my shield tablet. it's no game changer.. if anything, it's nice to remote play, but if i wanted to do console gaming, I'd just play on my console.

Because mobile gaming masterrace!
