I'd say the difference in HyperCard and Visual Basic is that they also define their runtime environment. The IDE can grow with the runtime. Writing tooling against a vast runtime like the web is much more difficult and daunting.

A 1.0 would need to address a large enough surface area of the web to be useful. There's also a discordance between hand-coding "friendly" HTML/CSS and what would be exposed in a WYSIWYG tool. Further complications are all the new and old bugs in browsers.

That said, every day I was working on Hype 1.0 in early 2011, I would nervously check Hacker News for a "Show HN" post for a HTML5 animation app that would steal the thunder; luckily none came. This is even more surprising given Hype exports were mostly compatible with Internet Explorer 6 -- such an app could have been written long ago.
