Back in 2001 Microsoft's early betas of Windows XP contained a user interface dubbed "Watercolor". But only months before the operating system shipped Microsoft completely replaced it with an entirely different look and feel called "Luna" which became known as "Windows XP Style".

That move has created speculation that current Windows Vista look and feel, called Aero glass, would be replaced by a different look and feel later in the beta process.

However, this week's PowerUser.TV podcast has an interview with Microsoft developers who have confirmed that there will be no major change to the look and feel of Windows Vista from what is being shown in build 5270. In other words, Aero-Glass is it.
