Okay so here is what I know. I know for a fact that there is cfw around for the ps4. No its not public and it may not ever be.I merged your post in the ongoing Sticky for this topic... besides the PS4 Dlclose Exploit (through 1.76), the Chaitin Tech PS4 Exploit (through 4.05) and the PS4 Pro 0Day Exploit (through 3.70, possibly higher) it's pretty much as you guessed... a waiting game.
There's always a chance something more will be revealed by Fail0verflow at CCC 2016 but I wouldn't bet on it... as always, time will tell.
I have that CFW too, it bricked my system, so i had to unbrick it by connecting my Nintendo 3DS, not the new one, the old one, then i had to insert a PS3 Jig into that and press XYZ and what do you know it was unbricked, i am now playing Uncharted 5 on my Xbox ScorpionSo to sum it up on what I know for sure. I have seen cfw on a ps4 running at firmware 1.76 and I have a copy of the firmware to try if I want to. The problem is that I don't if it will brick the system and I don't know of a way to unbrick the system as if yet. I have seen pictures of loaders working on a ps4 running on firmware 3.50. I have talked to hackers / friends that have been working on the setting systems and know that there are things that they are working on with firmware higher than 3.50.
