On October 4, 2015, Shaft announced that Kizumonogatari will be released - not as a single film, but as a 3-film series: Tekketsu, Nekketsu, and Reiketsu. These are the three adjectives that Koyomi uses to describe Kiss-Shot, meaning "iron and blood" (as in Bismarck), "hot-blooded" (emotional, impassioned), and "cold-blooded" (cold, calculating), respectively.
The first movie, Tekketsu, premieres on January 8, 2016. There's a new PV out for it, distinct from the old PV from back in 2011. Premiere dates for the second and third parts are as yet unknown.
There is actually a list of theaters in Japan that will be airing Tekketsu, so I think we can rest assured that this is not an elaborate Shaftian trolling effort.
At the time Tekketsu was announced, no information about outside-Japan airings of the film was made available. However, Aniplex, which is the producer for the Monogatari series, has been fairly good about securing outside-Japan airings for its past films, most notably the three Madoka movies. So there is hope.
