Adobe is going to release details on the latest incarnation of its Creative Suite on 23 September, but a leak by Amazon has revealed what we can expect.

Screen grabs and tech specs have appeared on the eCommerce website for Adobe InDesign CS4 - the widely used publishing design package that is part of the Creative Suite.

The leak suggests that InDesign CS4 will be available from 1 November and will boast a whole host of improvements including SWF file export and conditional text.

Amazon says on the web pages (which have now been taken down): "New Adobe InDesign CS4 software breaks down the barriers between online and offline publishing".

"Now you can create compelling print materials, immersive content for playback in the Adobe Flash Player runtime, and interactive PDF documents all with beautiful typography and stunning design."

"InDesign CS4 professional page layout software is the ideal tool to deliver sophisticated layouts for traditional and online media."
