Nope, Terrio's doing some rewrites, but there's been no mention of JL or MoS 2. I love how it's all about "it's a Batman movie guest-starring Superman and Wonder Woman, now." Why? Because all the focus is seemingly on Batman? That's the public's focus, that doesn't mean it's the filmmaker's. Snyder has made it pretty clear that this film ties into MoS (okay, maybe not clear, but, regarding stuff like the destruction in Metropolis, and Superman's actions, he's coyly acknowledged that there's going to be direct fallout, and said events are probably why Batman is involved to begin with). We put the focus on Batman because he's new; we already know what Superman's going to look like, in general. There's just a curiosity that needs to be satiated. Point is, it's people that are getting it in their heads that this is a Batman movie, not filmmakers. Maybe I'm wrong, but, even if it is a Batman film, this is your MoS 2.
I bet we see an "official" Man of Steel 2 some time after JL, to coincide with Wonder Woman and Green Lantern (with Johnson as Stewart) films. I wouldn't be the least bit surprised as well, if they "Hulk" Batman, saving him for cameos and team-ups to put a bit more distance between Affleck's and Bales (which I think is a missed opportunity).
