I think chapters 577 - 580 of One Piece are also pretty big…so February issue getting the covers is fine.
They really, really, really better not drop a chapter of One Piece though. The magazine has been down almost 100 pages for months...they have plenty of room to add more while not taking anything out. Plus factor in that previews of crappy Genkaku Picasso are now done w/ the December issue.
So that leaves only One Piece, Naruto, Bleach, and Ultimo...with the addition of 5D's and Psyren, they have no excuse to limit OP to 3 chapters. The magazine is down to about 260 - 270 pages with just OP, Naruto, Bleach, and Ultimo...adding in 2 more series brings it up to what, 350 or so? Still short of the 360 - 400 pages the magazine used to be. NO EXCUSES VIZ. FOUR CHAPTERS OF ONE PIECE.
Any less - 3 chapters per month or 36 per year and we fall way behind again in no time.
