Thought this was common sense?

No, not at all. It would just need to an internet connection during remote play sessions. Just like ps3/psp.

So what?

He doesn't even know if they did? X'D

Actually no. At least with the PS3 it had the ability to do remote play off of its own private network, not through the internet. No reason to expect this to be absent in PS4. I know you're just joking in light of the competition but I couldn't help but correct you.

Every PS4 game that's played with the dualshock 4. For obvious reasons move and camera games will not be supported.

For the use of an optional feature rather than the entire console.

Yeah it would. But you can still play games offline unlike that other console. You would also be able to turn off the "always online" feature if you wanted to. I assume it would work the same way as Ps3 does now. 

Woo, haters got started early in this one.

Still, what this tells me is that a lot of the Vita/PS3 features we've felt were under-used were really Vita/PS4 features. That's encouraging. It always felt like a bit of a letdown that some those nifty sounding functions were never used very often but now we know why.

better luck next try.

OT - looking forward to hearing more.  there has be be a reason vita has that accessory port and my monies on some sort of ps4/vita interaction.

is there anything that uses the accessory port at the moment?
