You will be able to run existing MacOS software on the new hardware under emulation. The Dev kits run emulation fairly well on a 2 year old iPad CPU so I would expect whatever new hardware they release will as well.
Existing Mac software should "just work" due to Rosetta.
Most Mac software should be ready with an Apple Silicon recompiled version when or soon after they ship. Apple has been showing how easy it is for most software to retarget the new chips will very little work.
Edit: Thanks to the replies letting me know that Rosetta is still a thing. I somehow forgot. Updated.
