So is it safe to assume that Apple will book 100% of the first production runs for this new process as well?
Example; Apple didn't use any 7nm EUV variant in A12/A13. While Huawei used it for their SoC. Having said that MBCFET, or more commonly known as GAA was originally scheduled for 3nm in 2022, so giving another 2 year to bake should help.
So yes, if everything were executed to absolute perfection, then we should see a 2nm Apple Silicon in 2024.
Note: While Wccftech has gotten a lot better in the recent 12 months or so, I still wouldn't put them into reliable and trusted source. It is good for rumours and entertainment, but that is about it. ( Personally I would rather not have it appear on HN )
That doesn't mean that Apple is interested. At least right now. Processes also tend to be improved with time.
1.000 US$ no, but... I would not put it past Apple to make a literal system on chip. Like, one chip with everything on one die stack: CPU, GPU, RAM, cell modem, voltage regulators... the only external components would be ports and whatever cannot be reasonably expressed on a silicon die (e.g. coils for voltage regulators).
