Sad there's no MP3/CD support.....apart from the odd AAA game, that's basically what I use my PS3 for...as a media player for my A/V reciever Home theatre system. Quite a few people I know do the same thing. Sony may have under estimated this a little. Hopefully it doesn't take too long for them to enable these features?
Basically all you mentioned is pretty much on my wishlist as well. One small feature I would like is the ability to appear offline. I know they had the comment hack, but I would rather the true ability to do it.
Overall I am thouroughly enjoying my PS4 and all it has to offer. I've been playing it since day one and have noticed some things I hope Sony addresses in a future update.
Current OS Version (US): 1.52
Wishlist for future update:
1. HDCP on games is still preventing content creators from capturing raw HD content from the PS4. As it stands now you need an HDCP stripper to use external capture cards.
2. Ability to sort friends list by what console their on. (PS4, PS3, Vita, etc.)
3. Home screen themes. I love the blue but it will eventually get old. I realize this is mainly due to the fact the console is new and will be addressed soon.
4. Playstation App on all mobile platforms needs to be optimized. Right now it feels really clunky and most links take you to a web browser.
5. Have an option to delete all messages or mark all as read.
6. Add sharing to YouTube. Facebook is nice to share among your friends in real life, but YouTube allows sharing to a much wider community.
As updates get released I will add/remove items to this list
I'm sure I didn't cover everything, so if you have anything to add please reply with what you would like in a future update.
