That's a bummer. Glad we keep all of our old consoles over here.
When I was having problems with my Microsoft account, the customer service rep (who was VERY helpful and polite, I have to stress) did ask me while we were waiting for one of his superiors to try and address a problem, "So I have to ask, if you have an Xbox One, why are you still downloading and playing games on your 360? Just curious." And I basically was like "That's just how I roll, man," and then I mentioned how I was playing my NES a couple'a weeks ago and the guy was like, "...WOW."
But yeah, I gotta replace my original Xbox so I can play "MK: Shaolin Monks" one'a these days, too. I only watched my wife play it for a bit but it looked awesome.
