This is in French:

It says that Battlefront III is still in development, however it might not be out until next year in 2010. But that means that there still is a chance that it could come out this year, in 2009.
Also the website that the information was from, http://gonintendo.com/ says that they were asked to pull down the information.
This information is from Activision, who publishes LucasArts games in Europe. Looks like they accidentally let the information slip! Now if only we knew who was developing it...
