Koops, King of Cowards.
They will do something about this year, that is for sure, but one thing I see being brought up that I doubt would happen is a new Paper Mario that supposedly celebrates Mario's 35th anniversary. Why? Because it's Intelligent Systems who is in charge of the series. And why is that a problem? Well... another big series made by Intelligent Systems celebrates its 30th anniversary this year as well. If they're gonna focus on one it would definitely be that one more than a Mario spinoff that Nintendo is already gonna provide things for the main series anyway.
