The Waves team is currently tightly lipped about the current state of the development. They are not giving out any promises. I like this attitude. Better not to promise anything and overdeliver then promise too much and disappoint.
Or maybe they think it is no longer necessary to hype because they already got your money.
But in all seriousness this is a cycle that I have noticed in an ICO. Too much hype at the beginning and then silence after the ICO. It is clearly them following a marketing strategy. But now we can only hope that they are silent because they are busy working on the project. Let's be patient.
