You may never lose track of your gaming schedule again, as it looks like a calendar is being added to the PlayStation 4 as part of a future firmware update. Eagle eyed gamers spotted an extra icon on the promotional images used for the European version of Journey's dynamic theme, and it very much alludes to some kind of on-board almanac.
Exactly what this will do is unclear, but looking at the screenshot it seems that you will be able to flag certain occasions. Perhaps this will keep a log of your gaming activities over time, as well as alert you about new releases and key events. We'll reach out to Sony to see if we can learn more about this – in the meantime, tell us what you'd use a hypothetical PS4 calendar for in the comments section.
