Actually, I just installed (yesterday) Ubuntu GNOME Beta 2 amd64 from a LiveUSB created by UNetbootin to a 8GB USB Drive and the installation done successfully and Ubiquity was working JUST FINE and YES, I have chosen: "Try Ubuntu GNOME without Installation" so from my side as per my tests, everything is fine. I haven't tested i386 Beta 2 yet though.
