But the rest of what you say holds a valid point - Adobe may be shooting Flash but it stands to gain with Dreamweaver. You could argue that Adobe Flash is the only real option for developing flash applications whereas websites can be created in notepad if you really wanted to, and that's true. There likely will be some conversion away from using Creative Suite products, but Adobe is sure to have to done the maths; they're not going to pull a stunt like this if they're not absolutely certain that they have the brand and product loyalty to make it profitable.
