Almost all Windows applications with GUI (WinForms or Native) use GDIPlus.

But this technology is quite old, and it shows many limitations.

Alternatives are WPF, or Silverlight, Flash? But Developer Tools like Visual Studio and Delphi still use GDIPlus as reference.

When will this change? ANd moreover: will there be a portability? Like the Delphi VCL will in future be ported to a new technology maintaining backwards compatibility? (for ex TButton is GDI, in future it can be something else).

**UPDATE**: Maybe my question can be stated as "will future OS render GUI Widgets without GDI+ but using newer technology, a kind of builtin SIlverlight/Flash?"
