No, Adobe CS4 won't be released on that date. September 23 (that's a tuesday) is the day when Adobe formally announces Creative Suite 4. The announcement will be streamed by Adobe to those who are interested. Signup for it here : adobe.istreamplanet.com
We have seen the beta version of some of the titles in the Adobe CS4 lineup back in May popping up in some forums, especially Dreamweaver, Fireworks, Flash and Photoshop. Adobe CS4 will be available in 32 and 64 bit versions (this is for Windows users only). Sorry Mac users you won't be able to enjoy the 64-bit version, you'll just have to wait for the coming of CS5.
