Cryptic Studios' Executive Producer Craig Zinkievich and included new combat footage and info. in an interview on MSNBC for Star Trek Online preview.
Length 3:18 video
I believe this new combat in-game footage is the first time we have seen space battles and phaser fire on ship interiors for this game as a video, with stereo sound.
In the video we also see the new The NX-91001 ship go into Warp leaving a blue trail behind. We also see the NCC-79719 new Oslo class ship flyby, NCC-95032 HAWAII (ARIZONA class), and another unclassed Federation ship. We also hear some of the new music underneath the voice.
At 3:02 there is a really nice wide shot of a Borg cube fast approach and full stop in front of what looks like a Enterprise-D and scans it with green light. Very similar to shots I've seen on Voyager.
FYI I found the NCC95032 here which should help you in classifying ships:
