Well, Yen has two Korean manwha coming out (which I generally don't cover on this site.)
And Little Brown is releasing the 5th Haruhi Suzumiya novel, which features Snowy Mountain Syndrome, the first story to be released here that isn't yet animated.
But that's it. Frequently when the first or second of the month falls on a Wednesday, Diamond treats it as a '5th week'. So no Viz blitz here, folks. Move along.
