Hi
Dreamweaver is only an HTML editor with a few bits added. any serious coder (and I'm not one) can do anything DW does using a simple text editor.
DW like WA products just save you time and a lot of the learning curve, however nothing can beat a good knowledge of hand coding when de bugging etc.
If it's ideas you want then there are plenty of shops around and most designs could with time and effort be made to work with PS3
HTH
