Woodoworkery: Well one more day will tell all
While they say "through November," that doesn't necessarily mean that they'll make a change December 1. It just means that they're guaranteed through the end of the month. It could be extended.
A while back when I contacted customer support on a related Nike issue, they said that they had not (at that time) set a concrete date. Admittedly, however, that was at the end of October when I had that email exchange.
By the way, in one of these threads about Nike equipment, one of the moderators did tell someone to "stock up" on the Nike balls (or something to that effect).
