As per other threads on this, they’re already coming out. Spesh Epics are landing in stores now (and selling like the proverbial warm gateaux), and plenty of others around too. See above re Trek.
Couple of things…
More companies are going to move away from the model year concept and release what they have when it’s ready. Even more sensible to do this given…
Supply chains are a mess, it’s going to take 6 months or so for them to be anywhere near ‘normal’. Some suppliers are giving very tight allocations of bikes between now and January, or further ahead. Lots of stuff on order is already sold anyway!
Interesting times…
