Preview at WWDC likely in June, followed by September launch.
Apple Reminds Users of iWork.com Discontinuation on July 31
Dear iWork.com user,iWork.com launched as a free beta in January 2009, with Apple intending to eventually offer the service with tools for collaboration on iWork documents for a fee. The service never exited beta, however, and with iCloud offering new options for moving documents around the company has decided to eliminate the program.
Remember, as of July 31, 2012, you will no longer be able to access your documents on the iWork.com site or view them on the web.
We recommend that you sign in to iWork.com before July 31, 2012, and download all your documents to your computer. For detailed instructions on how to save a copy of your documents on your computer, read this support article at Apple.com.
Moving forward, you can use iCloud to store your documents and make them available across your computer and your iPhone, iPad, or iPod touch. Learn more about iCloud.
The iWork team
While iCloud does not replicate all of the features of iWork.com, Apple continues to expand the functionality of iCloud, with the next round of improvements coming with OS X Mountain Lion later this month and iOS 6 this fall.
