It stands to reason that the real lift from reuse is the positive impact it could have on maintenance. We spend a lot time thinking about design and development, but that really isn't the pain point for most companies. So how would SOA provide the kind of reuse that would have a real impact? I only see two options. In the first, we build services that are so fine-grained and so numerous that applications can be composed in an infinite number of ways. For this to work, there has to be metamodel that describes the features of these services in excruciating detail and (said repository) has to be endowed with enough intelligence to reason on its own about best choices, redundancy, dependencies, etc. I don't see anything like that available in the near future. The other option is a few giant services that do everything, but are so general in nature that configuring them for an application is a massive undertaking. SAP R/3 comes to mind, though the reuse is at a higher level (the software company's). Clearly, something in between is the answer, but we have a way to go before we have the kind of active, inductive, representational framework to arbitrate an architecture like this. 75% of a Fortune 500 company’s IT budget is spent on maintenance (Forrester).

The fact that service-oriented professionals find the term SOA titilating should not constitute a technical strategy, however (even if does constitute a marketing strategey!) It is amazing that people still take about reuse even though that promise has been broken or wilted so many times, from object-oriented to service-oriented. The focus should be on productivity until it gets to the knowledge level. It seems tautological that knowledge would not be reusable. Interesting that business control over agility is not more front and center. Words like rules and architecture don't belong in such conversations (my view).
