Not selling mine, so it can't be everyone The ones I have seen selling theirs have been mentioning they are either going to get a Pro, or would get a Pro in the future.

I don't know why this would be impacting your decision though. If your concern is you want to pick the machine that is going to hold its value the best over the long run you cannot make any decision based on the data available at this point. My suggestion would be to just pick which gameplay style and theme you like most between X-men and AC/DC and then enjoy playing it.
