Same. I had my doubts initially, but Winter Soldier has been so well received, people may very well see him over Batman/Superman (or least see Captain America first).
Say what you will about the quality of the movie, the quality of Warners' marketing for Man of Steel was very good at promising a real event. Of course, this is going to lead to added disappointment for those who were already not too happy with the quality of Snyder's film, but that speaks very strongly to how well Warners' sold the fact they were bringing Superman back and you NEEDED to see it.
Now imagine the fucking eight-ring circus that's going to run from January til May of 2016 about World's Finest.
Even IF people have a great feeling about Cap after Winter Soldier (and they should) I have a hard time believing that good feeling is going to withstand the promotional onslaught of World's Finest, and the Avengers-sized novelty of FINALLY getting Superman and Batman on the same screen at the same time, not to mention Wonder Woman, as well as Lex Luthor finally making his presence felt.
You've got a new Batman, you've got Wonder Woman for the first time onscreen ever, and you have Superman's best-known villain. Warner's is going to make that feel cant-miss, even if the movie ultimately ends up being one you SHOULD HAVE missed.
I don't see Captain America 3 being able to keep pace with a marketing blitz fueled by that kind of novelty.
Cap 3 is bringing back the same team and so is MoS 2.
No, Man of Steel 2 is being written by Chris Terrio, not David S. Goyer, who is for all intents and purposes, not on the picture anymore. Snyder's regular cinematographer is new to the sequel, as well. So new writer, new DP, at least. Those two things can make a big difference in how you enjoy a movie.
