When Xbox 360 released with 512Mb of GDDR3, best PC cards from both AMD and nVidia had 512MB as well.
When PS4 released with 8GB of GDDR5, best PC cards had 4 and 6GB, respectively.

Somehow, I don't think anyone will be skimping on RAM in next gen as well.

That was also at a time when RAM prices were much lower (2013). I could get 64GB of RAM for under $299 then. You couldn't even dream of getting that much (DDR4) for that price now.

True, though many people, including Mark Rein from Epic (it was Geoff Keighley aftershow, IIRC), were quite surprised when they announced full specs with 8GB.
