Information has gotten misconstrued and twisted from source to source and dealer to dealer.
The truth from him is, the cases are being discontinued from shipping with any guitar they make. They are not discontinuing production. They also are not being offered as an upgrade when ordering a Collings.
They ARE, however going to be sold as an accessory. So...if you want a Collings made case, you can buy it after the fact. I'm sure this is all subject to change. But as of yesterday, this is the word.
It's unfortunate, but economics was the deciding factor. A lot of folks are fine with the TKL's. I for one am not. Therefore, I have Collings made cases.

The choice is yours. After the fact.
