I have edited OP with new links (DeftonesLive edits of the live performances of Smile and Melanie for example), and re-edited info.
A few years back, Nico (deftones-argentina here) has provided me with an audio clip of the fan-named "Dallas". It was different from the one that leaked, with an extended intro and a weird cut in it. I don't remember where he got that from.
Also, a few months back while I was doing some research on "Eros", I found out through their last interview before Chi's accident that the record was tentatively set for release to January 2009.
I also found an interview from mid-2008 where Chino said they were planning on a small-venue-only tour to go back to "those roots" per se, and they were going to play one full record at each show, one different record at each gig too.
