In a Q&A with Builder.au, Malcolm Groves tells us (emphasis mine):
The first half of 2007 will see a new release of Delphi, which while adding support for .NET 2.0 and 3.0, continues our commitment to native Windows development. We recognise the need to continue supporting Win32 developers, and in fact are continuing to extend both the language (eg. Generics for Win32) and the IDE for this platform.
Further out, we're adding 64-bit native support and as always, a very easy migration path for people to move their 32-bit code forward. On the .NET side, ECO, our model driven framework, continues to be extended, with support for VCL.NET being added, while we're updating the Delphi for .NET language to support the new goodies in .NET such as generics, nullable types, etc.
That's a lot of news... On the native side he mentions generics on Win32 and native 64-bit (although the "further out" seems to imply in a future version). On the .NET side the expected .NET 2.0 support seems to be joined by a 3.0 support. Truly, the two share the same core, so if you support .NET 2.0 you are already supporting .NET 3.0, thanks to Microsoft nonsense versioning ideas... However, it might be tempting to hope Delphi will start getting support for some of the extra libraries that actually make up 3.0. And the new ECO features (VCL.NET in particular) should be a real bonus for those who like ECO.
Not everything here is really new... but it is nice to start getting public info (beyond the roadmap) of what is coming along.
