The PS4 was launched with a 28nm APU and with 16 512MB GDDR5 modules (8 one either side of the board).
It still has a 28nm APU but is now using just 8 1GB GDDR5 modules (all on one side of tho board).
A PS4 slim will not come to market till the APU is on a 14/16nm fabrication process. And at that time Sony will probably go back to the clam memory design of the original board and have 4 modules on either side to further save space. They may take out the slot loading drive too and instead switch to a direct loading drive bay system.
The slim will probably be coming in at a $199 price point and all this will probably happen around the fall of 2017.
Don't expect to see the PSVr headset price drop anytime soon.
