Yeah , i understand cost is the problem here, but PS4 also first came with 8 GB GDDR5 when most  of High end PC GPU are 6 to 4 GB GDDR5 in 2013. And still they are managed to make a a high margin profit each of consoles sales. 

PS4 launched in 2013, when RAM costs were far lower. Can't compare this to that.

That's why it depend on how far mainstream GPU will evolve  in 2019.  It's possible for ram price goes down  in near future  or new tech are helping make the price of ram a bit lower  (like HBM3 rumored to have lower cost production ) will help shaping future consoles. My prediction are merely based on mainstream GPU that are existed today and possibly coming near future. I might be wrong thou.
