Apart the sad
and concerning license change issue (which has been confirmed by David I.
himself), XE3 has some features, in order to support Windows 8 new
'tile-based' interface (formerly known as "Metro").
Windows Runtime, or WinRT (not to be confused with
Windows RT, which is a tablet manufacturer only version of Windows
8) is a cross-platform application architecture on the Windows 8 operating
WinRT supports development in C++/CX (Component Extensions, a language
based on C++) and the managed languages C# and VB.NET, as well as
WinRT applications natively support both the x86 and ARM
architectures, and also run inside a sandboxed environment to allow for greater
security and stability.
WinRT will also be part of the upcoming Windows Phone 8 operating
It has been clearly stated that only Microsoft compilers and
runtime libraries (RTL) will be able to have full access to the low-level API
needed to create a decent RTL.
This has been done for security reasons, but it won't allow third-party JIT or
compilers to work as expected. Only Microsoft's C++ and C# compilers / virtual
machines have access to the needed API. Even if you do not have a JIT in your
language (Delphi is compiled and do not have any virtual machine), you would
need to access to some low-level API calls e.g. to mark some memory block as
executable (e.g. for virtual
Delphi is not able to have native support of WinRT, due to this
This is a known fact, but let us tell about "Windows 8 sideloading" feature,
available with XE3.
In short, even if you do not have 100% WinRT application, XE3
"Metropolis" (sic) styled Desktop applications have some potential to
behave like native UI applications, even if not being
