The only thing Sony has ever promised when it comes to firmware updates is Suspend Resume. Everything else has been community input and request. The standard functionality of all promised features out of the box, the playstation already has.
It's so annoying that if Sony isn't exactly jumping off rooftops to promote firmware updates to things they don't want to promise, it's assumed they aren't doing anything. I recognize they could have more transparency but as of right now, if they want to keep things tight so people expectations aren't running rampant and they start to over promise on things just to one up a competitor, then let them do that. It's either wait or leave.
The PlayStation as of right now works and doing what is intended. All that other stuff will come. These constant debates on what other want only proves exactly the reason why they keep it under locks.
Funnily enough, major updates on any device we own are always yearly. The Xbox is generally the only one that does monthly updates. iOS, neither Android or mostly any device for that matter does monthly major updates.
