Can someone tell me differences they've found or know of related to the code generation capabilities of System Architect 10.4 & TAU 3.0?

The main focus of SA is Enterprise Architecture and Data Modelling, with flexibility of notation and capture/extraction of this information. Tau is UML 2.x-centric and is aimed at users who are more model-centric whether that's for systems engineering or SOA architecture-thru-design-thru-software modelling. There is some overlap, e.g. SA provides BPEL with animation, and Tau can animate UMl; activity diagrams which have similar capabilities to BPEL, but that's an advantage because it means a Tau user can animate a UML-modeled business process. Similarly SA's codegen allows an SA user to get a start into software development if that's needed.

Like all generalisations this isn't completely accurate but I'd say that SA is more in the strategic (I've heard this called 'hand-waving') space whereas Tau is more in the technical modeling space.

SA's codegen isn't the prime need of SA's users; it provides basic class-outlines. On the other hand Tau is much more code-oriented (but doesn't have the same wide range of notations and Data Modelling as SA), so in addition to strong UML 2.x MDA/MDD modeling if you need them it supports C/C++/Java/C# codegen and integrations to IDEs like Eclipse and Visual Studio .Net for round-trip to software development which keeps the model consistent with the code.

So it's something of an apples and oranges comparison of SA and Tau; they have different sweet spots in the business, with some overlap (e.g. SA has some codegen, Tau can simulate activity diagrams) which helps make them more useful.
