Sony's President Shuhei Yoshida went on twitter today and announced that you will not need a PS+ membership to be able to share and stream your gaming experiences. This comes in light of Microsoft stating yesterday that you will need an Xbox Live Gold account to use their gaming DVR. This is yet another blunder by MS after they decided to keep their 360 model which does not allow users to access Netflix without XBLG. The PS4 will still allow you to stream Netflix for free as it had on PS3.
While you still need PS+ to stream and share your multiplayer gameplay, it still benefits those gamers that like to upload or search for walkthroughs for single player games, solo campaigns, and trophy guides.
