If you're going to use the car analogy, it was like 4DS were handed the keys to a new car (megabit chips) with a prototype engine (memory array) that they developed in the engine bay. They sat in the drivers seat, pushed the start button and the engine didn't fire up. However, when the mechanics got onto it, they were able to pull the engine from the car and fire it up on the bench (the advanced testing reported in April) Other engines work in the car fine so the mechanics have concluded there's an issue somewhere in the gearbox (the etch).
