depends on Vega. AMD indicated recently that they are targeting upto titan xp performance range with vega. That is motivation for Nvidia to launch Volta.
Below from an interview that Tom's hardware conducted
QUESTION : I know you won't be able to say much, but how does Vega compare to the GTX 1080ti and the Titan XP?
ANSWER : Vega performance compared to the Geforce GTX 1080 Ti and the Titan Xp looks really nice.

If AMD falls just short of their performance targets and Titan XP is still a bit faster then Nvidia will be comfortable. But if it matches or slightly beats Nvidia then they have motivation to launch Volta faster.
