How much longer until Resmed stops Airsense 10 C2C production?

[GoodNightRestGuy]

Hi,

After reading so many good thing about Airsense 10, I am thinking of purchasing Airsense 10 C2C from our sponsor, to replace my DS1.
From what I found online, Airsense 10 was first introduced about 10 years ago, and the C2C was just released recently.

So, I was wondering, how much longer until Resmed stops making Airsense 10 C2C?
If Resmed is going to discontinue it soon, then I am thinking of buying two of them, since it's on sale now.

Or is it a bad idea?
