Massive Attack ADVANCED vs. Official release

Hi !

I'm wondering what the differents will be from the advanced release to the official release. I have a theorie, maybe interessting:

3D always told, that he producet a huge numbre of tracks and they have to choose witch of them will be on 100th window.

Maybe MA released total different tracks in the internet as advanced release to "cheat" peoples. in february the official will contain different tracks from those you downloaded ...

one argument is, that they already told who will feautering 100th window: it is sinead o'conner and BLUR-Singer Damon Albarn, but Damon is NOT on the Advanced release !

second argument: in their past albums it was always a instrumental track at the end of the album. ... ther is also a 2nd version of ANTISTAR in the net who is only instrumental ... maybe the real ANTISTAR .. but maybe only a fake-verison ...
i but the song on my server www.buema.ch/out-of-space/antistar.mp3 ... it sounds as MA, right ? .. does anybody already know this track ??

so, what you think about these points ?
