If you take a look at the "internet" trailer -- it's not just the ending that is different -- it's been reedited. Beginning at 1:17 is when then changes occur.

1:17-1:19 -- "the wait is over" moved from end to this slot, removed is a panning shot of the crew on the bridge, and the battle scene just after this is fractionally reduced

1:24-1:26 -- scene where Krik has a confrontation with Spock is slightly different timing between the two trailers.

I think it's better! Particularly with old spock at the end.

Can't wait for May! Much more exciting (by appearance) than the old show ever was! Would like to see a bit more of Sulu and Chekov in any upcoming trailers.
