Yeah, was about to mention that game when Nirolak commented about it a couple of pages ago (but wasn't sure it was already out, and I kind of forgot about it).
It really doesn't make sense. I mean, 220 songs is insane for any rhythm game, let alone Hatsune Miku. Even Project Mirai DX has "only" 50+ songs, and that's including all those from the first Project Mirai.
Is there a special occasion (Miku anniversary?) for them to do things that way?

About Yo-kai Watch 3: I don't see it being delayed at all. No way Level-5 is going to give up on that sweet summer holiday money. There is no real reason for Level-5 to delay it either (it's not like the game is stuck in development hell or anything). Besides, looks like marketing machine is already going. Since January, anime has been focusing a lot on YW3 Yo-kai.
The "silence" surrounding YW3 isn't too surprising. YW2 wasn't even announced before April. It's Level-5's usual MO for Yo-kai Watch games. Next month is when they'll start talking about it.
