is d20 support static, or are there going to be upgrades?

[mirtos]

While the d20 system wont be changing, a lot of us still play.

There seems to be lots of work on the pathfinder, and I get that, and maybe from a business sense improving the d20 product doesnt make a lot of sense. I know the encounter builder went to d20, but it went to all systems. Id like to see improvement to the editor, which have happened in pathfinder.

Is the d20 support stuck? Or are we going to see work on it? If its stuck, please let us know.
