One of the things mentioned a while back was more specifically of that this year would potentially have more original content than there is of intellectual properties.
If this seems to be the case, especially with The Conjuring now out; it may bring the IP count at potentially a smaller window than the past three year's.
I think Blumhouse is happening, but that I think it's something that can be announced later than before, simply due to that it's not as large of a property than per say, Conjuring, The Shining or American Horror Story.
