I expect 10 gig to be enough for mainstream including 4k to be honest, from a purely gaming standpoint.
The unknown is things like RTX IO.
I said the same weeks back I accept, but this new comment is from now looking at the console specifications, the xbox series X e.g. has 16 gig of VRAM, but only 10 gig is allocated to game rendering. The Series S designed for 1440p has 8 gig allocated for rendering and I expect it will get nowhere near to utilising that.
