Capping out at a relatively low 16 GB, I'd expect to see the nano get a memory boost that will make the 16 GB model the low end (given its only $30 cheaper price, it's hard to see the point of the 8 GB model).
N'iji na 16 GB dị ala, M ga-atụ anya ịhụ nano inwe mmetụ ncheta nke ga-eme ka 16 GB nlereanya dị ala (nyere ya naanị $ 30 dị ọnụ ala, ọ na-esi ike ịhụ isi nke 8 GB nlereanya).
