In the opinions of many fighters and myself, the battle/rematch between Mino/Fedor is between them and has nothing to do with the GP tourny. It's a 'coincidence' that both ended up in the finals, but let's be clear on what belt's we're fighting for.
For example, had Mino won that fight, there'd still be a rematch to unify the HW belt. Now that this debacle happened, they would have to hold 2 more fights between them to settle all of the business.
Yes, it does make sense to have both belts up for grabs, but it cheapens integrity of the tourniment IMO.
