complete and utter nonsense
they said, they work on the new 7.x encryption, which was blocking eshop acces on 7.1 emunand and now is completely blocking emunand on 8.0, also the games, that require 7.1+ fw are affected by it
so when they release their new firmware with the 7.x encryption decrypted, it will mean, that emunand will work again and eshop access will be back, by no means will it mean, that a 7.0 firmware sysnand 3ds will be gateway compatible
we know, they are working on exploits for 5.x+ sysnands, however stating, that the NEXT firmware will already include such a feat is completely nonsense or otherwhise they would have announced it, because they have been saying, they work on exploits for higher firmwares since gateway's release and if they were by any means close to it, it would have been announced in a big way already
