Sony has been hinting at a big version 5.0 firmware update for the PlayStation 4, but... what does it entail, exactly? Eurogamer has an idea. The site has obtained release notes that hint at at least a few tangible upgrades. To start, PS4 Pro owners will have the option to broadcast their gaming on Twitch at a brisk 60 frames per second. That's nothing new for the PC crowd, of course, but it's a big deal if you want to showcase a fighting game or shooter at the same frame rate you see on your TV.
