If's it's DLC related, they wouldn't have been able to piece something together in just a matter of weeks in response to the bitching, it had have already been in the works. So, if they do show off some sort of trailer for soon to release DLC, then they didn't just cave in and violate their "artistic integrity", it was planned from the start. But I guess if they just talk about theoretical bullshit and show off some spread sheets, then we know that they've bent over and decided to take it.(Course, they're gonna make some sweet moola from the whoration.)

Here's hoping it continues from the destroy ending, if they go the epilogue route.

I think that depends on how substantial it is. For all we know, this could just be a patch where they put some of the content back in that they already had and ripped out to make the ending more ambiguous.

I'd be surprised if they ret-con the whole ending. They'll probably just "add more".
