There were no engineers there, as they had all left by Tuesday, but this is the best information I could get from him.
1. The OLED display of the Solo S3 is being used mainly because it uses less power, thus extending battery life. It's not something they plan to use on other detectors, at least at this point.
2. He didn't seem to have much technical knowledge, but from what I got out of him, it appears that the Solo S3 is some sort of modified M2. According to him, it's definitely not an M4. However, he claims that the Solo S3 performs very close to that of an M4. I told him that I would hold him to that and contact him after our next GoL if he turns out to be wrong.
3. He admitted to me that his Passport iQ has terrible Ka rampup and that it goes off at full blast on Ka band almost the entire time he gets an alert, so he clearly understands the rampup problem. However, he says that nothing at Escort is done accidentally and that there is some purpose for the awful rampup. I can't imagine the amount of genius it would take to do that on purpose.
4. I had a long conversation with him explaining that Escort is losing favor amongst most enthusiasts(basically everyone but due to the fact that all of their detectors have poor reactivity and terrible rampup. I told him that I have to compliment my 9500ci with a V1, because of these glaring deficiencies.
