Could this mean the death of MP3?

I found this article on the Musinat website:

"Musinaut interactive music launches MXP4 technology, a breakthrough interactive digital multimedia audio file platform offering artists and music fans an enriched and dynamic music experience. Going live internationally the MXP4 file format takes the current digital music and multiplies the experience to make it 4D. This enables digital music to be more expressive, interactive, adaptive, and surprising. Using the MXP4Creator software program, professional and amateur musicians can now create a single file containing different arrangements or 'skins'. For example a rock band can add acoustic, dub and a cappella flavours of their latest single. The very adventurous can add skins in completely different musical styles. All these takes are contained within one interactive MXP4 file. MXP4 technology means that artists no longer have to decide on a final version, they can now lay down several versions depending on what the different band members prefer. Solo producers using Logic, Cubase or Ableton can now include more than one bass-line, vocal or guitar track. The technology will then play back each arrangement based on the rules decided by the artist. This gives the finished work an extra fourth dimension. Depending on how much control the artist or producer wants this can stretch to thousands of possible playback variations of any given song. Music fans can listen to MXP4 files using the free-to-download MXP4Player. They simply select a skin to suit their mood or, if they are undecided, they can use the 'auto mode' to let the technology seamlessly choose for them. A surprise quality also occurs when an unexpected instrument or section arrangement appears in playback giving the end user a music experience closer to the unpredictability of a live performance. The artist can get closer to the listener by adding multimedia content to the file. Text, artwork, photographs, and lyrics can easily be added to the file to show up during playback. This lets fans find out more about the artists and his music."
