Depends what you consider a swan song. Its likely the last 3m December we'll see for a while from any system in the USA / Americas, as Wii will be down next year and 3DS will cut into DS.
My assumption has always been Nintendo would cut the Wii price in Spring 2011 to $150, and launch Zelda in Nov 2011 with filler content (Mario Sports Mix, maybe Pikmin 3, Rhythm Heaven Wii, Xenoblade) a couple third party items (De Blob 2, more Udraw games, Conduit 2, et), and possibly a player's choice line to keep interest going by tapping the late adopting, price conscious masses who bought PS2 after 2005. If Wii is $150 for Nov-Dec 2011, and Zelda launches, and then retailers offer more discounts ala 2009-2010, buying a Wii with two games could be as little as $100 - an absolute steal. So I wouldn't write off holiday 2011 yet - Wii is just entering the point that PS2 enjoyed in Nov-Dec 2005-2007, where it became the cheap legacy system with lots of cheap software.
I don't think a 2m December in 2011 is out of the question yet for Wii.
