My memory is slowly coming back as I read more GAF.
So Sony have 2 live streaming partners now:
Twitch Joins Ustream On PS4, Will Be Freely Accessible For All Users
http://wegotthiscovered.com/gaming/...-ps4-will-be-freely-accessible-for-all-users/
Perhaps they will add Nico Nico for Japanese gamers (like they did for Vita).
Niconico requires a paid account to stream on their channel (生放送).
I think It would probably be a gamechanger if we get to link PS+ accounts with niconico accounts to allow streaming though!
One can dream that it may be something announced @ 9/9 announcement.
