do people still not know what the suspend/resume function is?
with PS4 firmware 1.5 you WILL BE ABLE TO:
-switch between your game and other apps (ie: multitasking)
-allow the PS4 to download things while it's asleep (much like PS+ users have been doing on PS3 for a long time)
-wake up your PS4 remotely via Vita or the PS App on a smartphone
with PS4 firmware 1.5 you WILL NOT BE ABLE TO:
-pause your game, put the PS4 to sleep, and then come back later and turn it on, bringing the game up immediately right where you left off.
so that's what's missing until they add it in via 1.6 or whatever. then it will be just like Vita when you hit the power button while in a game/app. THAT'S ALL. simply the ability for the PS4 to freeze the RAM state while an app is active. they probably have some issues with it they are ironing out, as they have it working perfectly on Vita. i've even had my Vita refuse to turn on because of low battery while it was suspended, and once i charged it, i turned it on and it brought me right back to where my game was. magic.
