"New 3DS" is the latest 3DS console from Nintendo due for release in 2015. It was announced on 29 of August 2014. It will feature "New 3DS"-specific titles that are not playable on older 3DS models, which probably implies new encryption keys.
According to official sources, the following changes have been made hardware-wise:
- Faster CPU
- Better 3D screen technology
- MicroSD-slot instead of normal-sized SD-slot
- NFC support
- Two circle-pads instead of one
- New buttons ZR and ZL
Based on disassembly of certain sysmodules for code added/changed with in the 8.0.0-18 update, it appears that the "New 3DS" has the following changes:
- They extended FCRAM from 128MB to 256MB.
- They added another VRAM (?) of 4MB.
Going by the 8.0.0-18 update, which added support for the mem-regions listed above, it appears that the "New 3DS" will use the exact same system-titles as the original hardware(with a new system update at launch, for old/new hw, as both seem to use the same system-titles).
