Thanks for the list, after a bit of price research, Most NEW 3DS without XL are limited which not cheap.The n3ds will probably come on lower than 11.0/11.1, see here for a list of serial numbers: https://www.reddit.com/r/3dshacks/comments/4vv2i2/new_3dsxl2ds_firmware_by_serial_august_2016/
Look like I have to stick with Old 3DS in my hand for now
