My 6th gen nano replacement just arrived with UPS. Got 8GB. Nice. It was pre-used. Not new. Definitely not new. Even formatted for a PC and had some french sticker on the back and some scratches on the top. The warranty is saying that it last until Dec 26th 2012 so thats good. I had quite some iPods failing on me in particular the shuffle with the same form factor so I am not too pleased about that.
What warranty is saying that? If you meant online it will change soon.
If you meant the one in the box it should say 90 days.
