Final 'Evangelion' Film Receives Yet Another Title Update

After the television broadcast of Evangelion: 3.33 You Can (Not) Redo in Japan last Friday (September 5), it was revealed that the next (and final?) film in the Rebuild Of Evangelion series is now titled Evangelion: 3.0+1.0, and is expected to open in Japan in late 2015 (which marks the 20th anniversary of the Evangelion series, and the year that the series is set to begin in).

Could this mean a time travel or new theory on death and rebirth of universe?
