The survey asset was great when we built it 6 years ago. Since then it's been added to and massaged, but it has some inherent design flaws. Knowing what we know now, and taking advantage of ajax technologies, we can make the survey much more user friendly and powerful at the same time.
The new editor is all drag and drop, making it very easy to rearrange questions, and create branching options.
We'll have all the standard response types, and of course users can fill in their own options should the survey administrator allow them to.
There will be dozens of range answer types in the new survey, and you can create your own.
The old survey supported branching, but the new one does it so much better. For example, you can very easily leave out questions that can only be asked if the user is of a certain age.
