Capcom has announced via twitter that, due to unexpected issues, Capcom's kunoichi fighter will arrive later in June, along with the cinematic story mode.
"We wanted to clear up the confusion around the release of Ibuki in #SFV. She will be released alongside Story Mode at the end of June," the first tweet reads. The following tweet confirmed rumors that she had originally been planned for May, "We planned for her to come out at the end of May/beginning of June but there were unforeseen delays. Thank you for being patient."
Expect more information on what's to come to Street Fighter V soon, as Capcom has since started a new blog among the Capcom-Unity.
