Supposedly the last Rebuild movie is slated for Winter 2015 but that's only from a Japanese magazine and the movies have been delayed multiple times. Also official website has no release date.
I still think it's worth watching. If you get the chance, try to watch em fast and then go watch the 3rd rebuild movie in theaters:
