if Xbox One X can have 12 GB GDDR5  on this gen why not go nuts on next gen. Also future PC GPU will also go nuts. Even AMD has GPU that support 64 GB HBM2. And also even if it's imposible "a man can dream " . XD 

Why not go nuts? Simple. Costs. Unless you're okay with another PS3, then sure. Have at it.

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.
