First, I'm surprised Selina said yes but not as much as I should be since I read King's interview. He dropped enough hints in there for me to believe she might say yes more than she'd say no.
Now, onto my prediction. It's not going to last. Batman isn't very good with romance because he keeps pushing people away for various different reasons. So, my prediction is that "something" is going to happen that causes the engagement to be broken off. I'm not against Batman being happy, but through the decades he's been in comics he's been a loner when it comes to romance. Every single one has failed, some harder than others. He's even tried it with Selina herself a few times and it didn't work (at least, in the past it didn't).
So, as much as Batman deserves happiness, I just cannot see this turning into a marriage, settling down and having kids. Something is going to happen to mess it all up and Batman will go back to being single again.
Agree? Disagree? Why? Sound off below.
I think the engagement will be broken off, but, as it was with Lois and Clark, I actually do see Selina and Bruce putting it back on again and getting married eventually.
