You can read the official announcements of Delphi 2007 for Win32 and Delphi for PHP on CodeGear web site. There should also be an article on the developer network site, but at the moment the site is reporting the error : "SQL Server does not exist or access denied".

The Delphi 2007 description underlines many times Vista support (combined with continued support for Win 2000 and Win XP), refers to the DBX4 database architecture, and mentions a " VCL for the Web" with AJAX support I've never heard about before... but I guess I have an idea about it. There will be a Professional and an Enterprise edition.

CodeGear claims Delphi for PHP " is the first completely integrated visual Rapid Application Development (RAD) environment for PHP". It has an architecture very similar to Delphi, but it supports PHP for writing code, a PHP-based component library, and the ability to integrate with existing PHP open source libraries. There are a couple of screen shots.
