Capcom's Japanese Twitter account for Okami appears to be teasing an upcoming announcement.
“Sorry I’ve been kind of out of touch lately," said the account (translated by Gematsu), "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 a holiday period in Japan that runs from April 29 to May 5, and Gematsu also points out that the latest issue of Japanese gaming magazine Famitsu is teasing an announcement for its issue due out May 9.
Okami was an action adventure title helmed by Devil May Cry and Bayonetta director Hideki Kamiya, originally released by Capcom for the PlayStation 2 in 2006. The cult title has seen subsequent re-releases on the Wii in 2008 and PlayStation 3 in 2012.
A Nintendo DS semi-sequel, Okamiden, was also released in 2011.
