It sounds like modularity wasn't a big design consideration. With a modular design, you can replace or upgrade components and use the rest of the hardware for the additional testing. If each new system renders that prior design obsolete, there is more than a bit of waste. And extra cost. Let's hope the retired hardware serves some purpose along the way, at least for marketing purposes. They could conceivably show off the second or third newest system at trade shows with most of the latest functionality, and with very little risk to the ongoing development program.
