The Delphi and C++ Roadmap has been updated. It contains only updates for the native side of the fence. According to Nick's blogpost a separate update is in the make for .NET.
In short Tiburon is planned for second half 2008, focusing on:
1. Connectivity (Enhanced Datasnap)
2. International development (read Unicode)
3. Delphi language Enhancements
Commodore is planned for mid 2009 and will focus (among other things) on native 64bit compilation and parallelization in the RTL.
For all the details go checkout the roadmap.
