Two names popping up in this delphi.non-technical thread for new Delphi versions. According to the thread:
Delphi Spacely - Delphi for Vista (Win32 and AJAX)
Delphi Astro - Delphi for PHP
The source of this information is a Swedish reseller. More info in Swedish through this link.
Although not yet confirmed or announced officially by CodeGear this sounds very interesting to me. (It is by far the first of April so......)
Keep an eye on CodeGear for possible announcements the coming days.
