Adobe is hosting a webcast to publicly unveil Creative Suite 4, their next-generation graphic design, video editing, and web development application package, on September 23rd. Advance registration is requested in order to obtain viewing instructions. No specific details on the content of the webcast have been announced, and the release date, package options, and pricing for Creative Suite 4 remain unknown.
Adobe announced public betas of Dreamweaver, Fireworks, and Soundbooth in May, and additional information on the Photoshop CS4 interface was revealed in June. Early reports of an October release for CS4 were contested by Adobe, although this may end up being fairly accurate, as most Creative Suite 3 bundle packages began shipping less than three weeks after its March 2007 unveiling.
