Batman/The Flash

I've been wondering what will happen with the DC and Watchmen universes...are they colliding? Will they ever meet? I love all the DC universes and I'm wondering if they could ever collide with completely other stories and make different universes? BUT if you expect to find some solid answers in this..don't! Nothing really happens, this seems more of a strong Batman/Flash title that doesn't really solve any mysteries with the button yet. The story was good and the illustrations were also very nice. ~Ashley

[They go back to Flashpoint universe which is one of my favorites! I also had no idea that Jay wasn't in the rebirth universe! I'm wondering what happened to the other Justice Society members and if he will come again into play with another story. (hide spoiler)]
