I guess maybe the Sterling is having somewhat of an identity crisis maybe? The instrument has an interesting history, as originally it was a 4 string version of the Stingray 5, which had a lot of differences in styling and electronics from the Stingray 4, enough that it was almost a different instrument.
After 2007 the Stingray 5 was switched to the Alnico Pickups, and the Sterling 5 was brought out. Then there were the sterling and stingray "classic" models, as well as anniversary models.
With the full revamping of the stingray line, I guess the question is, what can be done with the Sterling line? They already are a more light weight design than the Stingray, they have the roasted maple and stainless frets, and they use the Ceramic design pickups everyone has loved for decades. I'm not sure any type of change is really wanted, except maybe 18V electronics?
