Adobe CEO this month: "To the extent that an improved HTML standard accelerates innovation and consistent reach for web content, wea€?re very supportive and clearly from the perspective of our tools, we will support the creation and management of HTML content to the level that they want."
But before tooling comes consumer support. Making faster workflows to create drawings is predicated on consumers being able to view those drawings. There's still quite a way to go.
(The Adobe Flash CS4 authoring tool isn't a general-purpose drawing tool. It focuses on various ways of creating SWF. Fireworks, Illustrator, even Dreamweaver are a little closer in scope to HTML construction.)
