...it will be a software exploit, not a hardware exploit.....lets face it if anything i would imagine the N3DS would of had less features, as they already have over a year of experience working with the original 3DS hardware......but really the hardware differences are minimal, i doubt it would cause any issues at all
EDIT, actually, thinking about it iirc the new3ds has a 4GB nand.....this might be why there is no news on emunand yet as they are still figuring how to go about redirecting a 4GB nand.....like would they need to make a 4GB emunand partition for new3DS's, or cold they just keep it at 1GB and disregard the extra 3GB in the system....idk, but i imagine that might be the reason for delays as thats the only real significant difference on the new3ds that i imagine would need extra attention
