I just searched youtube to see if there were any videos showing the "new" goodnites and this one compares the 2011 to the 2009/10 versions. THis years make seems at least 2 to 3 inches longer. This would be the longest they've been since 2003 or 2004 at least.

Can anyone here verify that they are this much larger?
