Re: Robin or no Robin?
A Wayne Enterprises logo. David Goyer said no other superheroes exist in suits yet. Superman is the first. He said Bruce is in Gotham helping people (in disguise I assume...heck maybe he's batman in the shadows but apparently hes not) but nobody else is suited up. Diana isn't outside of Themyscira yet so she's not discovered or called "Wonder Woman" by the media.
So that means Batman is about Supermans age. Maybe he's even a couple of years younger. But by the time we see him, he'll be in like year two. Early in his career but past the origin (think Dark Knight era but in a new style).
So Robin is too soon.
RIP to TDK Trilogy (2005-2012) but now let's bring on the Batfleck!
