For those who don't know, Treyarch usually releases trailers between 10am and 12pm PST. So for east coast, that would be between 1 pm and 3 pm EST. So do your conversions for your time zone. It's different for every trailer. The Preview Trailer came out around 10am PST, but other trailers have popped up around 12pm PST for different games in the past. So there you go. Stop making threads about it and be patient.
