Things that are bound to happen, and I hope happens now so I can call PS4 PS4.5:
- Gamertag change. This is already soft-implemented in the back end, and devs are encouraged and aware of this.
- External HDD: It's about time, Sony. You have zero reasons not to when even Nintendo is offering 2TB of external space.
- Console-wide supersampling for Non-Patched PS4 Pro titles. C'mon, Sony. Let us use that power however we want to, add a cap to it, and let the hardware/software work the magic. Provide a warning sign at every boot that games may be unstable compared to its Of state.
- PS1 emulation support. Not sure WTF you're waiting for when my shitty phone can do it too. Embrace your legacy!
- Customizing themes. Change background picture or music or tones to default setting for any theme. Add more font options, and more color options.
- Adding more options to sidebar (aka holding the PS button), like shortcuts to games or any other app, and even better, providing more options within like "Launch single player" or "Launch Multiplayer" for those games. Or adding things like Twitter feed to the sidebar/PS menu.
- Ability to upload content within PSN Browser to sites like e.g. imgur or streamable.
- Ability to play PSTV compatible PSVita titles. C'mon, Sony! Do it!!!!
