It seems you don't really need any of them. Since you have a Wii U, try getting Xenoblade Chronicles there.
I managed to find a copy when i was in San Franisco, incredible game.
If i were you i wouldn't buy the N3DS until a good advantage pops up. I am going to buy the N3DS, but i will do so just because my XL is the Zelda Edition and i want to preserve it.
