Our new vector drawing app, WebCode, is a nice replacement for Fireworks: http://www.webcodeapp.com/

It generates CSS, JavaScript+Canvas and SVG code from your drawings in real time and can also import PSD documents.

The generated code works great on both Retina and non-Retina displays. You can even preview how your drawings would look on Retina displays directly in WebCode. It inherited a lot of things from PaintCode (our app for Mac and iOS developers), which makes it very nice for user interface design.
