Is that it effectively killed Mark Millar's proposal for a Reboot Trilogy.
The story is here
I remember when he was first trying to drum up support for it after word came out that Bryan Singer was not really involved with WB on a new Superman film... and I didn't like his ideas then and I'm sure as heck happy that WB/DC decided to pass on his and Matthew Vaughn's 'vision' now.
I do disagree with the article's writer on the fact that Superman won't be seen on the screen again. He's too much of a cultural icon to be ignored (and there's that pesky judge ruling on having a Superman film in development by 2011 or the Creator's Estates can sue for damages) and if Batman can be resurrected after the god-awful Batman and Robin (which was much more harmful overall to the Batman film legacy than Superman Returns could ever be) so can Superman.
