Using MK4 nozzles with MK4S possible?

Since the MK4S is now available and the MK4 to MK4S upgrade kit will be released soon, I still have some MK4 nozzles left as a MK4 user.

Can I still use the MK4 nozzles with the MK4S, or will I need to dispose of them?

MK 3 -> MK 3S -> MK 3S+ & MK 4

From what I saw in several videos, the outer dimensions of the nozzles are the same. The changes in the HF nozzles are inside the nozzle. Also no mention of a change in the heater block. So I think it is safe to assume that we will still be able to use our "old" MK4 nozzles. The difference in the flow rate will probably be handled via different "HF" (or whatever they will be called) profiles for the new nozzles.

In the config Wizzard, concerning the MK4s we can see that there is profile for the HF nozzles but also regular .4 nozzles, so yeah pretty sure that the printer will be compatible with "old" nozzles

Prusa has traditionally been very good supporting such downward compatibility so it's safe to assume that old nozzles will be supported
