Game streaming is pretty cool when it works well and Sony's banking on PlayStation Now to bring a plethora of games to PlayStation 4 owners via the Gaikai streaming service they bought a while ago.
Well, it looks like that some folks are starting to get invites to a private beta. Sony is suggesting a wired Ethernet connection to your console and at least 5Mbps download speed. You'll probably be able to play if you connect your PlayStation 4 via wireless to your home network though and I think it would've been better if Sony had a wireless-AC in the console rather than wireless-N.
Even so, I'm anxious to see how well the service works as I've had good and bad luck with various game streaming services. Like I said, when it works well, it's pretty slick.
