We know four things, based on the last update TVLine gave:
Question: Any hint on the recent Blind Item you told us about? —Eric
Ausiello: It’s not a show on CBS, which leaves ABC, Fox, NBC and The CW. And the series in question is back on the air in the next month.

1) It’s not a CBS show.
2) It’s a Season premiere that airs this month, which rules out any October premieres.
3) It’s a returning series, which rules out any new shows.
4) The original article said that it was “shot last month” under secrecy, which should rule out any of the animated shows on FOX.
Here are the shows left that fit this category:
Thursday, 9/22
– Grey’s Anatomy
– How to Get Away with Murder
– Rosewood
– Superstore
– Chicago Med
– The Blacklist
Friday, 9/23
– Last Man Standing
– Dr. Ken
Sunday, 9/25
– Once Upon a Time
– Secrets and Lies
– Quantico
– The Last Man on Earth
Now I doubt it’s any of the comedies, but since the article never specified whether it was a drama show or not, I still had to include them. I think the most likely candidates aside from OUAT are Grey’s and HTGAWM, so tonight should prove interesting. If the Blind Item still isn’t revealed tonight, then that of course makes OUAT more suspect-able.
