It's almost not worth attending the Nokia Lumia 1020 unveiling event in New York City, just about every tiniest detail, picture and now video has been leaked online before the press conference. But that's not to say we're ungrateful. In fact, each leak has made us that little bit more excited.

The latest round of embargo-breaking content comes in the form of a series of videos accidentally released early by US carrier AT&T's YouTube channel. They have since been marked "private", but not before Engadget managed to rip them and put them up on its own video server.

As with all the other rumours and leaks, the focus is on the imaging capabilities of the 1020. However, one of the demo clips concentrates on the 720p video recording abilities of the new camera phone, which makes a refreshing change. It will have a 6x optical zoom for video and stereo audio recording, so will double as a HD camcorder nicely it seems.

Another of the videos also shows more than the already known about 41-megapixel sensor and optical image stabilisation. It highlights the phone's backside illumination sensor and Carl Zeiss optics lens.

I think we can safely say that the cat's well and truly out of the bag now.

Pocket-lint will be bringing you all the news and hands-on reviews of the phone and any accessories live from New York City as it happens.
