I just posted an updated version to Codeplex of the Web Client Guidance now called Developing Web App: Building Responsive Modular Web Applications. This version includes updated documentation with graphics and links to other topics.

We decided to delay the release to MSDN so that we can update our JavaScript to exclusively include jQuery and jQuery Plug-ins which aligns to the recent announcement by Scott Guthrie at MIX10.

So go check it out and give us your feedback.
