Regarding S9 vs AirSense 10 differences, for those who care about battery operation (camping, fishing, hunting, power outage backup, etc), note that the S9 is still the lowest power consumption option.
12 Volts DC power consumption data at 10 cm H2O (extracted from Resmed Battery guide):
S8 II Autoset -- 0.84 A
S9 Autoset -- 0.55 A
A10 Autoset -- 0.93 A
Above data is with humidifier OFF and non-heated tubing for S9, A10.
Also, the DC converter for the A10 does not seem to be out yet. An S9 DC Converter could be easily modified to work with an A10 by cutting of the S9 DC plug and replacing it with one compatible with the A10 (voiding your warranty in the process, of course). Both devices are spec'd at 24VDC @ 3.75 A (90W)
I use both the S8 II and S9 when fishing or camping. I get about 4 nights (≈30h) and 6 nights (≈45h) respectively with a 4 lbs, 222W-h Li-Ion battery pack. I prefer the size of the S8 II when I am out in the wild and that's my go to choice unless I need more than 4 nights of autonomy. The A10 would be inconvenient for camping, not just because of its increased power consumption but also because it is larger than either a S8 II or S9 (sans their humidifier).
