The people who are doing the translations have not stopped yet and not about to give up. I haven’t checked back for any info on the translation but I just did it now and on March 1st 2008, they released some screenshots of their progress. It looks like its going well and hopefully it will be released this Summer if not this Winter or next Spring.
Here is the link to the screenshot page of their project in progress: http://clannad.thewafflehouse.net/index.php?page=screens
Be sure to keep checking back here or their site for updates on this wonderful project. I downloaded the CLANNAD game before in Japanese and I believe it was 2GB. So you may want to download it and burn it on to a DVD or something and wait for the project to be finished and released.
