same here toriburu, although remember that a) 60% of their interviews (give or take) result in invites and b) after my interview I was told they would try to get through as many apps as possible for decisions, but by no means to assume you're dinged if you don't get an invite before the holidays as it is likely they just didnt get to your app for 2nd review. So there's still hope, it may just mean the later interviews were on the bottom of the stack, or that your specific app was (or c) we're dinged and just don't know it yet).
For a sanity check, anyone who's gotten in interview in the later batches (12/5 on?), my guess is probably so, and who knows what's going on...
