Before Round 1 Even Starts, Thanos Is Signed On For A Rematch?

Collider reports Josh Brolin has confirmed via his Instagram, he was about to begin filming on the untitled Avengers 4. Meaning we now officially know Thanos does not die in the upcoming Avengers: Infinity War. I feel like I've been trying to repeat that sentence to myself all day long. Who thought this made sense to let out? The Russo's have already crushed the rumors of Avenger 3 & 4 being a two-part series, saying 4 would be a entirely differentmovie, so this can only mean a so many things. There's the highly unlikely chance Thanos becomes a Loki-type, keep around because we need him kinda thing, the chance Thanos "wins" the first film, Thanos comes back for the rematch of the century, or "big surprise", Avengers 3 & 4 are a two-part series. I would accept any of these, as long as they're done right. Well except the first one, that would mean Thanos in a cell & I just can't really wrap my head around the notion. This is just a strange thing to announce if they're really trying to get away from this being two parts. That being said, I'm predicting a cliffhanger ending for Infinity War. With Skrulls on the table thanks to the details released at D23 from Captain Marvel, there's really no telling what to expect for Avengers 4. What do y'all think? Cliffhanger? Let's talk about it in the comments, like, & share.
