I feel qualified to answer this one, (as I went to the Borland UK conference a few weeks ago... (And saw the very thing working =)
They are bringing out Delphi for Linux (x86) and down the line C++ builder for Linux. The visual component library (VCL) has been rewritten as a cross platform library (called CLX and using QT for the visual bits). They have also added things like Apache support so you can recompile ISAPI dlls into Apache shared objects (at least that's the idea).
Delphi 6 for windows will allow you to use either the VCL for windows only, or CLX for cross platform.

All in all, rather cool stuff... =)
(I do have a basic empeg image tool written in delphi, which created the files for the old display program. I might have to update it now... =)
