It might have passed unnoticed in the middle of all the Tiburon blogs, but I think this is really relevant. CodeGear launched docs.codegear.com, the new central location for products documentation. From there you can download the latest help files for all products and in various formats (including PDF!).

What might not be apparent, as you first visit the site, is that portions of the documentation, including portions of the Delphi help are now available online for browsing. For example, you can find the help page about properties at:

      http://docs.codegear.com/docs/radstudio/radstudio2007/RS2007_helpupdates/HUpdate4/EN/html/devcommon/properties_xml.html
    

It is not a CodeGear MSDN, but it is promising... and reasonably fast for now (I guess it might get slower if many developers find it).
