Super rumour: they say a beta version of DOOM III (stolen, of course), appeared on the net and can be found with edonkey2000.

I'd like to remind that beta versions of Unreal2 and UT2K3 have appeared the same way before. And what if they didn't manage to get DOOM III to Quakecon 2002 wherer they promised to show it?
