I've wondered this same thing. I'm on HW 2.5, due a 3.0 upgrade, purchased Dec, 2018. Wondering if I wait it out and see or go ahead with a 3.0 upgrade. There's no guarantee on the future I get that, but I'm not really missing out on much right now without the 3.0 upgrade. Perhaps if the FSD really gets great in the next 6 months/year it'll change my mind.
