This FB post says: [Confirmed] : They already have the name for the new single to be released in coming months.

It's been spread through the web a rumor that Tokio Hotel will soon release a single. They have not yet reported how quickly they will finish the album. Just like the rumors on supposed names of the album, this is just another rumor that comes when the band is on recording process. There is nothing said by the band, any information about the album remains secret.
