Whoo that's awesome! =D
Simon & schuster is 99.99% accurate with this stuff.
I found the second Naruto speed up release dates on that site about a week and a half before Viz announced the second speed up. Sure enough, they were right.
I also don't want to get my hopes up….but it's kinda hard not to! XD
--- Update From New Post Merge ---
Interestingly enough I noticed Psyren is also going into a bimonthly release rate.....with One Piece volumes speeding up as well as Psyren....I'm a bit curious as to what exactly will be happening with the magazine in 2012. I'd imagine Psyren will be "graduating" if it's going bi-monthly starting with the 3rd / 4th volumes. They can't keep up with that release rate in the magazine.
Further confirmation that this is indeed accurate: Naruto release dates have changed as well.
Naruto volume 53 - December 2011
Naruto volume 54 - January 2012
Naruto volume 55 - March 2012
Naruto volume 56 - May 2012
