While you are correct that Paranormal #5 is coming out on that date...
"The Marked Ones" is actually the name of a spinoff of the series which is coming out on Jan. 3. Apparently they're not counting it as an official entry in the series, but they're calling it "Paranormal Activity: The Marked Ones". Yes, it sounds silly to me too. From what I've read, it has an all-Latino cast and the story is only vaguely related to the other films in the series. So we're actually technically getting TWO of these movies next year. I'm sure this will cause a bit of audience confusion...
Thank you. It is confusing..
And I still say the Paranormal Activity-Athon has grown tired and pointless ..
I didn't even realize the confusion until it was pointed out to me.. Thank you.
