Sunrise is master of titty twisting its market.
They use any excuse to delay episodes to build up hype for the show. Just look at how things went from last year to now:
1. Sunrise plans 25 episodes, the 26th for DVD.
2. Sunrise adds two recaps at the last minute to build up space.
3. TV airers go, 28 episodes? LOL NO, Sunrise feigns not knowing what to do.
4. Sunrise delays 25 + 26 so they can be re-written and re-animated four months after the main show ends.
5. R2 is delayed for a year, when it comes out at episode 3, someone leaks the video ahead of time which causes a scandal. It was then revealed to be LOL ACCIDENTAL.
6. China earthquake as an excuse to delay the episode again.
This is all supplemented by tons of NewType spoilers, insider tips from 2channel, seiyuu interviews, and a whole lot of other shit.
