Actually, even if Inoue will face a much more popular or so-called "big name" opponent compare to him, it's not the basis of where the fight will take place. Since boxing is associated with business, big matches should only take place at proven associated with a big market.
If let's say Marlon Tapales will have a shot at a unification fight against Naoya Inoue, just in case the Japanese monster won this match against Fulton, don't expect that the Philippines might be chosen as one of the venues even for consideration.
And besides, I see that guest boxers are even more determined to pulverize the host in front of its home supporters.
