Microsoft's Xbox One won't be the only next-generations system that will need to apply a launch-day patch before it can be used. Sony confirmed that the PlayStation 4 will need to have a firmware update applied before consumers can have access to some features.
The update 1.50 will be approximately 300 MB and will activate such features as Remote Play using the PlayStation Vita; second screen gaming using the PS4 Link app for PlayStation Vita and mobile devices; the ability to record and share screenshots and video; use of the Ustream and Twitch apps; the ability to play games as they are downloading; the ability for four users to log into the PS4 simultaneously; party chat; facial recognition and voice commands; the background music player; online multiplayer through PlayStation Plus; and Blu-ray disc and DVD player capabilities
Judging by the aforementioned list of features, it's safe to consider this a "mandatory update."
The PlayStation 4 will launch on Nov. 15 in North America and on Nov. 29 in Europe.
