Fireworks will never be updated to a CC version, since its development was stopped by Adobe more than two years ago in May 2013. There is no support either.
The code Fireworks produces is unsuitable for production work, but can be used for quick prototyping. You should not use the code in Dreamweaver.
Of course, you can still use Fireworks to edit & create images which can then be imported in your pages.
But as a product, it is dead.
