Prusa video: https://www.youtube.com/watch?v=VO2MaQrUcqE

TL;DR For those who don't want to watch 10-minute video:

MK4 to MK4s uprade kit: 109€ + shipping (MK4 customer will receive a voucher (except shipping cost))
Larger cooling fan
Improved cooling duct
high flow nozzle
NFC for app
some parts upgraded from PETG to PC-CF
MK4s still ship without an accelerometer. Prusa claims this isn't needed.
No camera.
No upgrades for the Prusa XL in the near future!!!!

other stuff:

accelerometer board
GPIO board

Personal Opinion:

This should have been the MK4 to begin with and shows once more how blindsided Prusa was. BambuLab put so much pressure on them that they had to publish the MK4 in the state it is.

Regrading the Prusa XL the trouble continues. This launch/printer has been riddled by issues after issue and now the statement that the improved part cooling won't make it to the XL in the near future.... My guess it that they screwed up with the XL and didn't consider large toolheads at the design stage favoring a 5 toolhead design over a 4 head option and now run into the same issue I do with the E3D (it can fit those 6023 fans but not like they mount it on the MK4s). For example, with my E3D tool changer, a tool must fit within a 85mm(w) x 60mm(depth) surface area.

For the technical side?

The larger fan is great as it allows to use fans with decent pressure at the target airflow with a low noise. Those 4020 found on most printers aren't a great choice.

High flow nozzle? Yeah ... nothing groundbreaking or new.

NFC and app? A year ago was prusa connect at best a beta. Maybe a an alpha as I would need to restart the printer twice a day because it froze/crash. The value here depends on if they meanwhile fixed it or it is still a joke.

GPIO board? Depends. Might be held back by the firmware as those things require macros to be useful and Prusa firmware never was build around this idea. Still nice to see them publishing this.

Yeah if I pay 3700€ for a printer, I expect it to work flawlessly out if the box. If I wanted something that just works pretty well, I'd stick with the 250€ printer I have now.
