The
Japanese Site for Final Fantasy IV Advance was updated yesterday with a pair of new commercials for the game (under the TV-COM section). They also added a few new desktops which I have uploaded to the site
Here.
The North American site is supposed to open soon, but greets visitors with a teaser page for now. The Japanese may get a fully functional website first, but North America still gets the game 3 days earlier (December 12th).
