256GB Galaxy Note8 version confirmed by a flier
It seems that the 256GB version of the Galaxy Note8 will not only come with quadruple the storage of the base 64GB model, but some premium goodies as well. There will be a promo in South Korea there that offers you a choice between an AKG Bluetooth speaker and a Nemonic printer (think PostIt notes with cloud integration).
The 64GB model will come with a coupon for up to KRW 100,000 off accessories like the Gear VR or a combo of case plus external 5,100mAh battery. These are just examples, there should be more options come launch time. This somewhat ties into the report of Samsung offering cases with the Galaxy Note8.
Note that a 128GB model is expected to be available in the West. In fact, the 256GB model may not be go outside of South Korea and China.
