The Playstation 4 took advantage of higher density memory modules for a similar cost.
Otherwise they would have had to double the amount of memory chips and costs would have blown out.

12GB or 24GB... I just don't see happening from a cost point of view, you would need a 384-bit memory bus to power that.

Duuude you can do 12GB or 24GB of ram on 256-bit memory bus, this is possible on GDDR6 but not GDDR5.

 

EDIT:

Since you usually ask for source for some random reason (you should find a source not me), this what I found

http://monitorinsider.com/GDDR6.html

"GDDR6 breaks with that tradition and offers in-between options. The standard allows a capacity of 8 to 32 Gbit, but 12 Gb and 24 Gb are possible as well. This will probably make GPU makers happy since it will increase the ability to segment the market based on the amount of memory."

"Today, a GPU with a 256-bit bus can only cleanly support 4GB, 8GB or 16GB. With GDDR6, they will also be able to support 12GB, while still maintaining a full balanced load with identical sized memories connected to each controller."
