I'm confused if I need to have my old 3DS with me in order to transfer data to the new 3DS XL when it comes out since I want to trade it in to get $75 towards it at Gamestop. Do I need the old 3DS and use system transfer for the new 3DS xl or do I just need my sd card with all the save data on it? I have 16 gb sd card for the 3ds and planning on getting a 16 gb micro sd card for new 3DS.
It says on http://en-americas-support.nintendo.com/app/answers/detail/a_id/13996 that you can "Transfer save data using only the microsd card with the New Nintendo 3DS XL" and that the "NNID, Friends List, eShop balance, etc will be transferred to the new system".
I've seen other posts saying I need to use system transfer so I am confused whether I need to or not.
