People would buy them for the same reason people bought them originally. Because they want a PRS at a more affordable price point. My only point has been, with the old ones that's exactly what you got. With the new ce it's close, but not the same.
Not the same. True.
The new pickups are much better pickups than the old ones, IMHO. Much better. Could be my fave PRS pickups ever.
Playability, can't say, haven't played a new CE yet.
Neck finish, I like the old nitro finish. I have one with the new "in the wood" finish on my WL McCarty. So not a deal breaker.
Scarf joint stuff, who cares, won't affect a thing.
Less body carve, ehh, taste fairy stuff as far as I'm concerned, especially given the price savings over Core.
Really the only significant compromises are a different trem and tuning machines.
Pricing, taking inflation into account: Old ones were much closer in price to Core, than new ones will be.
My own take: The recent 5 PRS purchases I've made have been 1 Wood Library and 4 PS guitars, so it's likely that I'm pretty selective/fussy. But for some reason I see the S2s and this new CE as great values. I was very impressed with the S2s I have played, and also examined at the factory at the 30th event. I thought, and still think, they're "real" PRSes. Yes, even with the hardware differences.
I see the compromises PRS chose to keep the pricing down as very minor, considering what's on offer. Just my two cents. If I wanted a PRS bolt-on, I'd at the very least play one of these.
