Paramount Announces "Paranormal Activity 4"

All I can say is "YAAAAAAAAAAAS!!!!", because I love the "Paranormal Activity" franchise and i hope it will go on for another few years, which it will because they're smart films. Paramount have said that they hope to get the fourth film out be later this year, sometime between August and October, like the previous films.
There's no news on who will be part of the cast or crew, but I'm assuming that Katie will probably be returning, because we still don't know what's happened to her since she stole her sisters baby boy at the end of the second film.
