GBR918 had asked about this only a few days ago. Apparently the Big Ten was listening.
From the official BTN release:
CHICAGO - The Big Ten Network will air the exclusive announcement of the Big Ten Conference's new logo, division names and associated elements at noon ET Monday. Dave Revsine will host the show, which will include an appearance by Big Ten Commissioner James E. Delany to discuss the announcement in greater detail.
Let wild speculation commence on division names.
