I'm torn.
On one hand, I like to think of newspapers moving the story along, especially when everyone has known the news for an entire day. Looking ahead suggests we're not just sitting on our hands waiting for others to break the news.
But one can make a persuasive argument about the importance of commemorating important events with a paper of record headline. No one would want to read, on Sept. 12, a newspaper front emblazoned with the words: "What's Next?"
I suspect we all have to make personal judgments about this. Saddam's capture, while important, certainly didn't have a Sept. 11 quality to me. Tweaking the headlines to suggest upcoming developments seems appropriate.
