Wasn't this rumour from before E3 last year? At least I read about it in a spanish website, so I'm not surprised if it's true.
Last Paper Mario I played was the wii one and I kinda hated the game. If it wasn't for playable Bowser that game would have been a complete shit for me.
NPC designs were so lazy that I was in shock when I played it the first time. Almost everything in that game is lazy and poorly done, the enemies, bosses, world design... I stopped playing it because it was so freaking boring. I got to a space stage and had enough of it xD
That's one of the few games I've played in the last few years that I stopped playing because of how boring it is.
Not hyped at all for a new pm game. If only it was a new Animal Crossing game :_(
