To quell my own feelings about this, I went through my inbox and found last year's email talking about December admits.
UCLA sent the email on December 14, 2011, exactly 1 year ago today, that said (among other things):
Our largest-ever group of December admits will be announced before the holidays to spread good cheer -- then more admissions and interviews will come after our school's winter-break closure Dec. 22 to Jan. 2So far, I haven't received anything to that effect this year, so it's up to you all individually to keep hoping throughout the holidays or just resign to waiting until the end of January. At least in another month and a half, we'll look back on this and laugh at our crazy selves for completely over-analyzing this situation

EDIT: @Luis -- thanks for your initial post. It's not that I don't believe you...it's that I don't
want to believe they'd leave us hanging after interviewing us so early on.
