A second Italian Blog (other than Gundamuniverse.it/blog/) claims the Unicorn Movie is indeed confirmed, backed up by a Youtube video showing the announcement made during a Sunrise press conference at "Cartoon on the Bay 2009".
The blog speaks of Takayuki Yoshii, Sunrise' CEO, confirming a 2010 release for a Gundam Unicorn movie, during this private press release.
