Maybe it’s an answer to the creality K1. I assume it’s a P1P, including all the things, needed to enclose the printer, like cable chain, glass door and top, MC fan and a dark plastic enclosure (maybe from X1). I like this. But I also love my self enclosed P1P. 
I don’t hope that the ‘S’ in P1S stays for ‘speed’, because this would mean, that my P1P is slow now! So I hope it means ‘special’.
