I love 2ch rumour mongers. They're expecting a 12th gen auditions at either the start or end of the Morning Musume spring tour.
It's blank right now, but stalkery wotas have observed that they clear the page right before each new audition. Before they announced the 11th gen auditions, the 10th gen audition information was wiped. And now we're at a blank slate again, so there's a lot of speculation that they're prepping for a new auditions process.
And then some enterprising wota hacked some data:

Created for 9th gen auditions.
Last updated after the 11th gen winner was announced. It's a blank slate right now, we don't know if there's going to be a 12th gen auditions, but I can hear the clock ticking!
EDIT: Note that the Masaru Funahashi guy is the stage production director for the 2010 Pikapika spring tour.
Some wota dug up his name.
