Computex is May 30th, so saying Vega wont be available that week doesn't means there is a long delay. Some sites are speculating Jun 4th others June 5th, and yet others saying late June.
There is just too much speculation and very little fact. All we really know now is that Vega will be at Computex, but wont be immediately available and will launch for the workstation and server market first. That and Vega will use 2 stacks of HBM2.
Any way you look at it, Vega is looking to be competing against volta as opposed to pascal. No telling how much faster voltla will be over the current nvidia lineup, it's supposedly yet another a new architecture.
