Just a little late with this, but Ambrosie talked about a possible schedule format if the league goes to ten teams. His idea is to play each division opponent three times (12 games in total) and six against the other division. That goes even further than my proposal (10 games in the division, 8 vs the other). Ambrosie's plan would cut down on travel costs (which he mentioned), and would likely eliminate any possibility of a crossover.

In any case, it seems he's no fan of a balanced schedule.
