Ok, yeah I see now...
Yeah, I'm not sure it's anything new, per se. I have several cases that have the two different types of support.
My 2018 WL Custom 24 came with a black paisley case with the support you're describing...large chunk of foam under the neck.
My 2018 WL Custom 24 Piezo has a brown paisley case with the two-sectioned neck support setup we usually see.
My 2024 WL Custom 24 has a case identical to the 2018.
My 2022 WL Custom 24 came with a black tolex case with the large foam block under the neck like my black paisley cases (only in black, not blue...and also felt, opposed to plush). I wanted a brown paisley case for it, so I bought one online and it has the two-sectioned neck support like my 2018 WL CU24P. Oddly, the latches on the brown paisley I bought separate are in slightly different locations than my other cases, core included.
All my core guitars have the black tolex, two-sectioned neck support system we usually see.
I've always been curious about the differences between the cases and why they're there.
