Hi All,
Thanks for all your replies and great discussion, it really helped us think through these issues.
For now, we have cancelled our order and plan to wait till March 1st to place a new order for the same configuration with FSD (yes, we will be paying the 15K for it). We will only take delivery if the car has HW4 included with it.
@mylapore I agree with you completely, we would gladly pay the 3K extra for the new hardware. Since the car is already damn expensive, another 3K is not that big a deal.
All indications are that HW4 release is imminent and it will be done first in Model X. For those of you interested in which indications I am referring to here, please look through Twitter feeds from @Teslascope and @greentheonly. It is mostly just rumors and speculation, but after following the company for 10 years, we know that this is how it typically starts.
Not sure if I am feeding a troll below, but the cars are a technological marvel as far as we are concerned. We have seen huge improvements since our Model 3 in early 2018 till the most recent Model Y. Further, even the 2018 Model 3 is a better car now than it was when we first bought it - the regular software update just keep improving the car's functionality. Lack of USS in the most recent Model Y wasn't a surprise, and we do miss the beeps while parking - but that is no big deal. The tone of messages quoted below and the fact that poster only joined TMC couple of weeks back suggests to me either a troll or carebear - I usually do not respond to these, but decided to make an exception this time. I want to make it perfectly clear, WE ABSOLUTELY LOVE OUR TESLAs and no other car comes even close to their technological superiority.
