Vega is the Furys replacement, the 490, was rumoured to be a dual 480, to compete with the 1070/80.
All Just rumors though, no-one knows anything concrete at the moment. I am speculating that small Vega will be a 490 and large Vega a Fury/Rage product with the 490 having GDDR5X and Fury/Rage having HBM2 and both obviously being on larger dies.
We will all just have to wait and see.
