The Japanese PSN page has put up a big update list today for Everybody's Golf (all in image format so it doesn't translate.) See what you can make of it from the screenshots. Looks like improved messaging, multiplayer and challenge features to me.
From the UK PS Golf forum, it looks like we'll be able to play those recent downloadable courses (Mt. Sakura, Northern Fox, and Mar Cielo) in the daily tournaments from next week. Not sure if those two are related but every little helps.
