Will the 6G Nano Get the software upgrade that is in New Nanos?

Just curious if anyone knows if the Nano 6g is Going to get the new softare that is included in the newly released Nano. I dont think this would be unheard of for apple, since Many of the Ipod touches received the I OS updates of the newer IPOD Touches, although I beleive the first one was for a nominal $5 fee. The new watch faces would be great, although, im not sure about the new Icon screen with only 1 icon on it. But the new fitness features seem nice too. however, none of these features would be any reason to upgrade my current 6g, as I think the new one is a 6G with minor software enhancements. Im not even sure what they are calling it? anyone know if they call it a 7g now? Is this really 7g?
