Just to give a little context, I have a background as a design-savvy developer (not a developer-savvy designer). I worked at an agency many years ago. I've been out of the design game for about 3 years and starting to get back in. Back then my tool of choice was Fireworks, but I just learned yesterday that Adobe is letting it slowly die.
So what are the mainstream next-generation tools for someone who's doing exclusively web graphics and interaction?
Or, since that question may be considered somewhat subjective or "what's your favorite tool", is there an authoritative source that can give a good view of the web graphics tooling landscape?
