So the A1 beta firmware has
The biggest IMO is the air printing. This likely being another anti-spaghetti thing. That or anti-clog which the A1 has already.
What is the likely this feature will come to the P1S?
Considering bambu has traditionally given all the printers the new firmware goodies in due time i would say pretty good. But this is 1000000000% speculation and I have zero proof so ya lol don’t take this as gossple
I’m can’t say for sure but it seems unlikely. The P1s have a very weak computer inside (lower power than the X1 and A1), and without new hardware will not be able to do some of the things the X1s and A1s can. This task looks like it heavily depends on compute to detect the strands via camera, etc.
I would like to see a PC plugin or other means to enable air printing and other failure detection via PC. In other words, use the power of a connected PC, to process the images from the printer camera, in Bambu Studio.
I wish as have had a few and one just recently. Job records as finished but the last bit of the print is fresh air
But won’t somebody think of the poor 3d-printed Christmas trees? 
There’s 3rd party systems that can analyse the video feed. Rig up an extra camera and connect to that. I’ve seen some built into Vorons.
Even the best are not fully accurate. Sometimes the print is just shaped like that, or the camera can’t see due to angle or part of the print blocking it.
