I just confirmed that with Pete at Kodak Professional Products (Ext. 19). Kodak has also just discontinued TMX in 5x7, where 320TXP will be the only film available as a stock item.

It doesn't seem like the 10-sheet boxes of 8x10 were to blame, since 5x7 TMX continued to be packaged in 50-sheet boxes, to no apparent avail.
