I just wanted to give you my opinion on this so it doesn't get misconstrued and I hopefully don't get bombarded with questions. Go ahead and read this if you haven't already and please read the rest of this post after:
I am not considering this real news. It certainly is NOT an official announcement of any kind. There are no official sources for some points (those about Daisuke Sato's health and the earthquake are true and appeared in his recent interview for the FCE volumes). To save time, I'm going to copy what I said in a comment in another post:
Some of the things on that list I knew from the Daisuke Sato interview in the new FCE volumes. Some of it is logical conclusion. A few points (namely the ones that talk about what they're doing to work towards a return), though, I simply can't accept as fact without viable sources. I want to believe it, but this has to fall in the likely-but-unverifiable category. I believe that this person did research and dug up some facts, but then connected them through his own inferences and speculation.
There is too much here that goes beyond any official word I have heard for me to treat this as real news. I'll keep my eyes and ears open, and hopefully we can start confirming some of these points. I think the real proof will come in an announcement when the next chapter is ready.
The part about buying new chapters is absolutely true and actually makes me suspect someone under Yen Press' payroll is behind this, in which case it would be absolutely true. We'll see!
I know this won't do much good, but PLEASE don't go around the internet touting this as absolute fact. This is interesting and very believable, but it's a lot like investigative journalism: When you take some disjointed facts and connect the dots in a logical way, people tend to believe it.
So there you have it. I will, at the very least, use this information as a sort of checklist when I look for official, source-supported info in the future. Until then, buy the manga to support the authors, be happy that someone somewhere is doing something, and keep checking back for more information.
