PS4 user interface leaked via test kit video

The user interface, more commonly known as a dashboard these days, for the Playstation 4 has not yet been revealed. However this leaked clip should give us some idea of what it could look like when Sony finally decide to do the big unveiling.

The footage comes courtesy of a very early PS4 testing kit (hence the crash which actually takes us back to the dashboard, enabling us to see it, in the first place).

We thought that the dashboard sounds were pretty much perfect (atmospheric, if you will) although there will likely be an option to turn them off if you want, just like with the PS3. The UI also looked very quick which will make a nice change from what we currently have with the Playstation 3.

What makes a good dashboard in your eyes?
