They will babble about 4 hour flight times (and not mention that they're talking about 4 hours at <50kts) but at the end of the day, everyone has to contend with the same battery tech. All current airframes in the category are looking at about an hour of 65% power. A good rule of thumb is that nobody is going to be getting more than twice the flight time of a state of the art quadcopter.
