As a previous developer at the New Berlin office a few years ago, I can confirm Integriclaim was written in Borland Delphi and does use Paradox on the desktop.
Most of the back-end server systems were being iteratively updated to C# .NET code. IntegriClaim Express (the web application) was written in C#, ComCentral had components here and there ported to C#.
I suspect the new software on the desktop may be written in JAVA since the MDA technical staff which reviewed the software back in 2005 were JAVA centric; however, it is also possible the software could be written in C# as well - since there was a history at the New Berlin office of using .NET.
There was talk of using Delphi .NET, however, I believe the consensus was to move away from Delphi syntax to C# or JAVA, and MDA's review may have swung the door to JAVA regardless.
I will say there was talk of the New Berlin development staff simply supporting the old Delphi code until the MDA development house in Canada could roll out a new Java-based product.
In any event, I'm quite sure the new product will be sound and solid - as MDA has a long history of technology products used in the defense and geospatial information industry, so the new product development will have benefited from a far better iterative development and testing process, and superior systems design.
