Check out the “obsolescence statement” on the Raspberry Pi product pages. The 3B+ will remain in production until at least 2028 https://www.raspberrypi.com/products/raspberry-pi-3-model-b-... and the 4 until at least 2031 https://www.raspberrypi.com/products/raspberry-pi-4-model-b/...

Remain in production could mean like the nano 2 W which is manufactured in such small numbers it’s never in stock.
It’s available to buy from several places https://rpilocator.com/

Not in the US it’s not.
Or it may require a large order up front.
There's nothing stopping a person from putting an ESP on a RPi B board format (or a Zero one), other than certain IO limitation. The upcoming P4 might be a candidate [0]. If you are interested in sbc in Pi form factors (B, Zero, CM3, CM4), then something I follow is CNX [1]. It will typically have notifications of any new Orange Pi, Libre Computer, etc.

It would be amusing if they used a pi2040 chip to drive the IO pins on such a board. I'm sure there's cheaper chips out there to do this.
It might make sense given pi2040’s PIO capabilities. Additionally, the RPi5’s io chip, RP1, might have some similar tricks inside.
The Raspberry Pi Pico has a fascinating peripheral known as the “Programmable Input/Output” (PIO). This device allows us to write very simple assembly programs to emulate a number of different peripherals and communication protocols.

RP1 is our I/O controller for Raspberry Pi 5, designed by the same team at Raspberry Pi that delivered the RP2040 microcontroller, and implemented, like RP2040, on TSMC’s mature 40LP process.

Raspberry Pi are used installed as components into third party engineered products, and Raspberry Pi brand holds no value to potential industrial customers if new products did not technologically exchange with existing such products. That is to say the exact mounting details, electrical compatibility, software compatibility, DO provide the value the "Raspberry Pi" brand offers if its competitors offered it.
What I'm saying is, if Espressif brought that new ESP-branded 32bit thing in the Pi 3 mounting dimensions and onboard eMMC and 1/5th performance at $35+9%, that kind of thing could outsell Pi 5 at this rate, and I wouldn't mind watching that happening.
