Hell Yeah it is the new trailer! Its just awesome! I cant wait to see this movie and this is not the official trailer for part 1 or 2 its just an overview kind of trailer for both parts.. part-1 trailer is different for which i dont have the links right now.. but i have seen the part-1's trailer in AMC when i went for a different movie.
it looks great but so did the order of the phoenix and half blood prince trailers and david yates screwed those two films up.
hey ! this trailer is from part 1 and from part 2 ......... and i think that it was epic like in the end when voldy is dueling harry WOW that was amazing and when he kills harry ( well the horcruxe ) it was really cool
They just showed it on AOTS and it is for both parts, the release date on the first half is November and the second in July of 2011.
It clearly states it is in two parts. Its a trailer for both parts.
