When artists release followups within a year, it's usually an attempt to move on from (and bury) what was a poor selling album. And since we can see that Joanne isn't selling...we know that this is the case. If that album was doing well, she'd spend at least a full year promoting it and then take a break before following it up. But it's flopping, so she wants to move on from it. I bet Interscope is looking at Gaga, perplexed at what she once was, what she isn't anymore and doesn't know what to do with her at this point.
