With all of the stuff that's announced at Comic-Con every year, I figured there should be a thread to consolidate everything. So if there's any announcements from Comic-Con you want to share, post it here.
I put a spoiler warning in the title, so if you don't want to see untagged spoilers, leave now!
I'll start off by posting what I posted in the Smallville Summer Hiatus thread:
James Marsters himself announced that he will be returning as Brainiac for the 200th episode of Smallville, "Homecoming".
