I don't think they had an issue with design so much as only having a single team as bottleneck for the entire product lineup. They really need the equivalent of Intel's tick-tock strategy where the designers can be going full speed on the cool new manufacturing techniques but a second team is just taking last year's industrial designs and shipping updates with current spec / capacity components so they stop drifting so far behind the market every time the design team isn't ready to ship a major change.
