I think I can say based on what I saw that the 2017 models will try to solve the list price commitment in a reasonable way, and also seems to work hard on some very important quality issues that people rightly note here (I think I know which but shouldn't say until it's out/confirmed). But mainly they made a point that they're trying to broaden sales and make sure they can sell everywhere. They do sound like they're aiming for larger scale for now, which means that the existing platform will just get tweaks for a little while.
For what it's worth, larger scale is strategically important to our concerns, since both parts are cheaper to order in bulk (meaning we should get better parts), and a technology investment is more justified with a larger sales base, and just like the ABS adoption, there was a large fixed cost and development time to bring something out. But it does mean that probably two more years will not feel revolutionary each time.
Naturally, they vaguely alluded to projects that spoke to many concerns on the forum, including mine. Hell, someone referred to me as "Mr. Rice" in the third person while talking to me before realizing I was that person! Spooky. Someone also said "Brian Trice", which always amuses me and is one reason I put the middle initial in.
I strongly suspect that just about anything we have touched on has had some kind of mockup/feasibility test; the question is how much bandwidth they have to carry those projects to market and of course which ones won't feel risky / unprofitable.
