We've known about this for a while (with a tweet immediately after the ratings came out) that Sasuke was pushed to next year. There was another tweet today as the formal arrangements were discussed in the first of a series of meetings for Sasuke 2015. Just thought it was cool that they are mentioning it so far in advance publicly.
True though for those who missed the original announcement it was done 2 days after the airing of Sasuke 30 (right after the ratings). Yesterday (this morning for us) they started officially the meetings for Sasuke 31. And yes it is the earliest they have organized for the tournament. I'm hoping all of this pre-planning works and they can get a successful reboot (obstacle changes, marketing, advertising, etc.). I know the ratings from this year rocked their world and they need to rethink the strategy of riding the old M9 fame. Those days are goooooone.
