Battlefranky from APforums has found Oda's "announcement"...and it's somewhat sad news for OP fans:
Oda [While Togashi's back it's been decided that the series will be taken out of the publication. It'll be shifted to a 10 week cycle instead]
Essentially as it's interpreted is this: when HxH is running, OP will be on hiatus. After the next chapter, there will be no more OP until the latest HxH cycle is over. And there is another catch: if ten weeks goes by after OP returns and HxH is ready, OP may go on hiatus again for ten more weeks of HxH.
The news is essentially craptastic: I know Togashi is weird but this is just the height of insanity. Why does Oda become his sacrificial lamb? Why not just rotate all successful series one a week until the HxH cycle is over? Why are the editors doing this...heck why is Oda going along with it? I just don't get it at all...and I fear what the other fans are going to say about it.
The only bit of good news I can take out of this is this: One Piece has possibly vaulted in my head out of the "Big Three" (where it was with Naruto and Bleach) and entered "untouchable" territory (where lies KochiKame and...oh, HxH)
