Flash is not an entire suite of tech. Its an application that makes one type of interactive file... Shockwave Flash. (.swf). Not much "suite" there.)
Flash (the app) is an authoring tool designed to make interactive content. At the moment, it only makes .swf content. But there's no reason it couldn't be updated to save html 5 or even blu-ray and DVD. The latter two are pretty restrictive, but Adobe's DVD/Blu-Ray app can save your DVD as flash. And Adobe Fireworks can save as flash, gif animations, CSS, etc.
