We haven't decided yet exactly what to make the new www.wikipedia.org project front page look like, but it seems pretty well decided that we do want to move the English wiki to en.wikipedia.org and set up some sort of multilingual and/or browser-language-setting-sensitive intro page.
(See: http://meta.wikipedia.org/wiki/What_to_do_with_www.wikipedia.org )
If there's no objection, I'm going to switch the URL redirecting around tomorrow, so that www.wikipedia.org/* points to en.wikipedia.org/* rather than the other way 'round. A new intro page can later be set up at convenience.
Warning: login cookies won't automatically follow over, so everyone using the English wiki will have to log in afresh after the switch even if you've got "remember my password" checked.
