If you're like me and you buy your manga in comic shops you may have to look elsewhere for most of Yen Press's July releases, or ask the store to order them from someone other than Diamond Comics Distributors. Apparently Diamond Comics has cancelled a number of the manga and manhwa solicited in the May Previews.

Brigid of Manga Blog emailed Kurt Hassler and he had this to say:

So far as the Yen titles on this list are concerned, these are not publisher cancelations. These are Previews cancelations which simply means that Diamond for whatever reason has opted not to make these titles available through their service. The books are all still very much being published, and retailers have the option of ordering them directly through Hachette Book Group or through any number of other wholesalers like Ingram or Baker & Taylor.
