A new Okami announcement could be set for next week according to a translated tweet from the official Okami account.
The tweet was translated by Gematsu, and it reads, "Hello, this is Okami news. Sorry I've been kind of out of touch lately, but I have the feeling we'll be able to drop a fresh announcement like WHAM! around the beginning of Golden Week, so please look forward to it. Right now we're on track with preparations"
Golden Week is Japanese public holiday taking place between April 29 and May 5.
Apparently Japanese magazine Famitsu, also has something to announce as soon as May 9, although this may or may not be Okami related.
