So this was basically a soft launch, with limited availability. Newegg is already sold out of 3700x and 3900x, and I don't even see the 3800x.
We don't know. Everyone sold out fast on the 3900x. It appears as though supplies of anything but the 3600/3600x were restricted, but unless we have numbers, nobody can tell.
So, how many zen 2 were sold just today if stocks are more&less limited?
We don't know.
Does the 3700 hitting its max power constraints under normal operation imply there would be virtually no overclocking headroom?
That's a misnomer. Watch der8auer's delid vid (it's in the benchmark thread) but I will break it down in my own language.
We saw this effect with Radeon VII: lower the temps, and you CAN get higher clocks (if you want them) without adding voltage. Cooling = headroom. Period. Matisse is the same way. You get more clockspeed headroom at 30C than you do 50C than you do 70C, and it is measurable. Same voltage, higher clocks. On Matisse, this effect is observable up to around 5 GHz (give or take) after which point the chip will stop scaling due to either process limits or cold bug. You're talking heavy negative temps there.
Then there's this:

This review also sort-of showed the same effect, where he put a 3700x on a simple watercooling loop with one rad (think it was a 360) with no fans. He dunked the rad in icewater and got extra clockspeed at stock running Cinebench.
With Piledriver, the old saying used to be: if you can cool it, you can clock it. With Matisse, if you can cool it, it clocks itself.
