Exactly right - This is right in line with last years rouse of Zarqawi being seriously wounded (this was a faked story). He was never wounded.
Will have to see what falls out regarding this with Al-Duri. But one thing is certain we won't believe rumors until we have solid evidence backing them up -
Getting Al-Duri is definitely of importance. Catching him alive would be preferable.
Alive would be better but harder. If he was really dead someone would itch to turn in the location and get paid.
Less heat to inform on a corpse.
