They will ofcourse copy Nintendo again and include a HDMI-cable

And links to YouTube.

Apart from the 'play out of the box' stuff (yes hdmi-cable looking at you), my guess would be one or two months of PS+ to get more people introduced to the insane service it offers.

No, i was actually talking serious. Maybe it's just a problem with my TV or whatever, but besides breaking easier, those silver cables often give me worse image quality, which doesn't make any sense because, technically, every HDMI cable should give the same image because of the signal being digital.

if it came with a game that would be like totes cool
and a coupon for Red Lobster.

-PS4 console
-Dualshock 4
-HDMI & Power Cables
-Eyetoy 3rd Gen
-Playstation Plus 3 month trial
-Big Ass Manual
-Voucher promoting the launch-window games
-Sony Secret Sauce

Everything you can expect, besides the HD cables.

i don't think ps+ will be availble on launch unless it is BC otherwise there is no games to give away, they won't give away ps4 launch games with psn+, like vita, they can provide ps+ after 6 months. BUT if it is BC or it is BC through Gaikai then ps+ is possible from getgo
