Singer Plans "Super" Sequel; Thinks About "Wolverine" Too
From ComingSoon.net: "According to The Honolulu Advertiser, Singer acknowledged that he has also been approached to direct the fourth "X-Men" movie, but said he wouldn't have time to take on another large-scale project before the next "Superman" gets underway. He is interested, however, in seeing the script for the "X-Men" spinoff Wolverine."
And from IGN Movies: "According to IESB.net, the working title for the follow-up to "Superman Returns" will be "Superman: The Man of Steel." The site says Warner Bros. had no comment. Singer advised fans at this year's Comic-Con that the sequel will be the "Star Trek II: Wrath of Khan" to the first film's "Star Trek: The Motion Picture," meaning more action and less talk."
So here we go again, basically.
