No other information is available about "Death of X" at this time; it's not known who is working on the title, or whether or not it is a new series, event, storyline or something else entirely. Marvel currently has two events in the works: the currently unfolding X-Men event "Apocalypse Wars" and the upcoming "Civil War II," which will also feature an X-Men tie-in limited series. A previous teaser for a Spider-Man storyline called "Dead No More" was released back in January.
Currently, the X-Men are in dire straits thanks to the Inhuman Terrigen Mist that has enveloped the planet. The Mist has caused the spread of an M-Pox, which has rendered the mutant race sterile and stopped the births of new mutants while also proving deadly to existing mutants. Whether this teaser has anything to do with this plot line remains unclear.
