I'm trying to avoid leaks as much as possible so I hadn't read that. Kind of hoping it's not true, I kind of like the version we've seen, it's different. Although rewatching the teaser the Bat symbol we see through the text of the title as it rises up matches the one shown in the comic. Still, tie-in or not hope it's a good story...that the sequel never acknowledges (just not a fan of "expanded canon" getting references in films).
Here's hoping that confidence isn't misplaced and they're right on banking on this. Still two spin-off series and a sequel announcement seem a lot for a film not even out yet.
