I haven't heard of any new SE models. Although I'm sure there are some coming, there always are. And probably some updates to a few current models.
I also wonder if there are updates to the S2 line coming... they seem to have become very, very scarce. Sweetwater hardly has any in stock. Which is very strange. Unless it's just plain a demand shortage. But I'm wondering if they're scaling back production in preparation to launch new models and updates, so dealers don't have to discount NOS pieces.
At any rate, I'm always hoping for more mahogany necks on SE models, and stoptail bridges on everything. Seems like a large majority of SE's have maple necks now - CU24, CU22, CU22 semi, Tremonti Custom. Don't get me wrong, I appreciate that some people like maple, but I think the classic recipe is mahogany necks, like we see on the majority of S2's and Core models. And I can't get enough of a stoptail on a Custom model. My first PRS was a flat top SE Custom 22 with stoptail... loved that guitar. Can't get 'em like that any more.
