Something is coming from Marvel, although we're not exactly sure what. The publisher sent a save the date on Twitter this morning urging followers to "tune in" on Thursday, January 26 at 10 AM ET for more information.

What this announcement could be remains unknown. It's not even clear if this is an announcement for Marvel's comics, TV shows or feature films, since all those properties share the @Marvel Twitter handle.

There's already plenty going on at the House of Ideas, though. The "IvX" and "Monsters Unleashed" events continue in the comics while "Iron Fist" and "The Defenders" prepare to make their debut on Netflix. Additionally, "Agents of S.H.I.E.L.D.'s" fourth season continues to unfold while Marvel preps to launch an "Inhumans" TV series on ABC this Labor Day. On the film front, this year has three Marvel films rocketing into theaters: "Guardians of the Galaxy Vol.2" in May, "Spider-Man: Homecoming" in July and "Thor: Ragnarok" in November.

As the save the date indicates, more information on this mystery announcement will be revealed on Thursday at 10 AM ET.
