another reason is that we can't share too much about what we're working on in case some journalist picks up some wording as promising some feature we can't deliver on. a lot of the stuff we're working on is stuff we don't know if we can deliver in time, in a polished enough form. so what we're talking about is what we have already solved, and which we believe is going to sell the device best to the people we target.
lastly, Certain Companies that have tried to do this for years are really, really interested in how we have solved the latency problem, and we don't want to help them.
