This is what I have found in my digging, I am going to spoiler it because it is speculation that makes a lot of sense. However, I would say that if you don't want to know anything about a movie leading up to its release you should probably just avoid these threads all together. We aren't looking to spoil anything but there is a large chunk of us that love to speculate and pick apart every little bread crumb leading up to the release. I think from now on pure speculation is free game in this thread. You have been warned!

Spoiler!

I have a legal background. The whole “v” thing, that is an adversarial thing in courts. When you go to court and you’re reading old court cases it’s “Smith v California”. The first name in the title of a court case is the grieving party. It’s the one bringing the grievance. The one saying the first party has a problem with the second party. And that’s the legal way that that’s set up. So when I look at that title, it makes sense that they left the “s” out of the “v” [in "vs."]. Now it makes sense to me. Batman is the one coming after Superman in this film. I have no doubt about that.

To me this makes a lot of sense. Batman sees the destruction these two aliens caused in Metropolis, he wants to make sure that doesn't happen to Gotham.. but he isn't just coming in guns a blazin', which is where Luthor comes in. More of a strategic use Bruce Wayne approach. I also think that this movie is much bigger than just Batman and Superman going at it, which is why they have cast so many other heroes for roles/cameos.
