All those things you have stated are coming to the ps4.
Technically, 12:01am Eastern Standard Time on November 15th, 2013, was 'after launch'.
Here is the laundry list of 'missing' features for the PS4, all of which I advocate and want (please note that I am purposefully not including tweaks to existing features) :
Whatever the next firmware update includes, at least one of these features listed above will likely be missing, and I seriously doubt that headset support will be one of them. When these features are implemented, I want them implemented right, not 'right now'.
- DLNA & MP3 support
- External HDMI capture support
- Expanded headset support
The PS3 didn't have DLNA support for over eight months, and I don't think we'll have to wait that long. I understand the argument that the PS3 supports DLNA, so the PS4 should start with that featureset and build, but am not willing to have lost any of the functionality present in the current build of the PS4 firmware to get it.
