Or also the people who have the old flash carts as well. It's the main reason why I still fire up my old DS Lite.
I highly doubt that they are going to have that in place. Nobody has found an exploit yet to overcome the encryption by software methods alone. Right now, the only thing that can overcome the cart encryption is a hard modded 3DS with custom made programming to basically force it to sign an altered save.
The best that we are going to have is Datel for now. Hopefully, the other guys like Bond, Slash, and Smea will find some way to exploit the same process using the current exploits that the flash carts use. However, even that may never come.
