Should Final Fantasy be back on Nintendo Consoles?

It's no secret that I'm a huge Final Fantasy fan. Hell I even named my cat after Lightning from Final Fantasy XIII. Back in the day the Final Fantasy games were on Nintendo consoles and they were great but when Nintendo didn't make the switch to disk based games the franchise moved to the Play Station. Now Nintendo has disk based consoles yet we don't see many new Final Fantasy's for them. In all honesty it doesn't bother me at all, but I do want to know why they haven't brought any of the main titles to the Wii, Wii U, or 3DS. The only reason I could think of is legal reasons or that Nintendo's consoles are held back by it's software. I know a lot of people will be mad that I said this but Nintendo consoles are almost always a step behind in technology. Perhaps there systems just can't do what Square Enix wants. Despite this I wish that Nintendo would get something because I would like to see my favorite game company have games with my favorite game franchise again.
