ThinkSecret reports that iWork '07 will launch next week at Macworld and is expected as "one of the company's more significant product launches of the year".
The new version of Apple's productivity suite offers a long expected spreadsheet component that has been previously described.
Sources have also passed along additional notes regarding features in Lasso, including many that will transcend all iWork applications, such as conditional formatting in spreadsheets, enabling images to be treated as content in table cells, and an iPhoto-like "heads-up display" interface offering image editing options.
Thinksecret has posted development screenshots of the application icon and application itself. They warn that the final shipping versions may differ slightly.
Amazon has posted placeholders for the expected iLife '07 and iWork '07 updates on their site.
