During Man Of Steel's final battle scenes, General Zod and Superman's tussle ended up tearing a space-dwelling satellite to shreds. The satellite in question was emblazoned with a logo that many people recognised as being Wayne Enterprises' logo - the company owned by Bruce Wayne AKA Batman. Everyone knows Batman is coming to the DC Cinematic Universe - he is one of the titular characters in the next movie, after all - but this particular Easter egg could point to Wayne Enterprises having some kind of involvement in the construction of space-based locations like the Justice League Satellite - in fact you should put your money on it. Regardless of that, it clearly indicated the existence of Batman, who will be portrayed by Ben Affleck from 2016 onwards.
