I read a Sena press release that the 20S EVO was released on July  7, 2017.

This is not true, you can't find it anywhere.  It s not for sale.  I called Sena and asked when it would be available and got a foreign person who gave me incoherent answer.

Same for the 30K.  Lots of ballyhoo but no projected availability date.

What's the deal Sena?  Are these real products or not?  I suspect the latter.  Al smoke, not real.
