Is Apple releasing a widget app called Dashcode?

Could apple be prepping a WYSIWYG widget-making app? Sure looks like it, if you check out screenshots in an Applenova forum thread that the Cult of Mac found. Looks like it has a few templates to use, along with javascript debugging and "a heck of a lot more!"

This looks fairly legit, and if so, my only question is: why so long Apple? Tiger landed last April, and Dashboard widgets were one of your staple marketing tools for it. Why are we only seeing an editor like this seven months later?
