Only new info I picked up is that it will only be offered with a 90kWh battery at this point. And I think he was referring to not just the Signatures because he mentioned a price just below 100k. This might delay quite a few orders until the X comes cheaper.
Keep in mind though that it isn't a pano roof; it's part of the windshield. I doubt it has any tint at all.
This is my chief concern; that it seems like an Apple-esque cool form over function that will prove annoying over time. Any time I've bothered to open my pano roof, the sun has been in my face and baked me until I closed it. I don't really want that feeling all the time.
