Simply put.... is there any? Flash Builder 4.7 came out in 2012... 3 years ago.
I see adobe rolling out new versions of AIR but why no concern over the existing Flash Builder bugs or creating new features?
Imagine a Flash Builder where when you add assets to your source folder, you don't have to clean project > close FB > open FB > clean project > pray > compile.
Imagine a Flash Builder where when you replace your swcs, you don't have to clean project > close FB > open FB > clean project > pray > compile.
Imagine a Flash Builder where you could select your Native Android or iOS library files and click "compile ANE".
I'm sure there are many many other wishes for AIR developers but these are a few of mine. I'm also sure the people over at Apache Flex would love an update... seeing as how they've had to have Adobe manually release .jar files to fix known issues (Flex New Project Issue - Flash Builder 4.7).... As far as I know, this is the only ever update from Adobe for Flash Builder 4.7 since release. An update for Adobe Flash Builder would do SOOOO much for inspiring the community about Adobe's faith in it's own superior cross-platform development suite.
I think I would do a backflip if I could get some insight from someone at Adobe about the future of Flash Builder. Chris Campbell or Joseph Labrecque maybe?
