This morning it appears that that bout has been put on the back burner, at least for now.
Instead of a rematch with Uchiyama it seems Miura is hoping to get himself a unification bout with WBO champion Roman Martinez (29-2-2, 17). From what we understand the idea of a bout with Martinez, instead of Uchiyama, would be to raise his profile on the international circuit with Martinez being known by boxing fans in Europe, Mexico, Puerto Rico and the US. Much like the win over Dib raised his profile in Australia.
At the moment it's unclear where they are hoping to stage the bout though it's worth noting that the contest was suggested at a press conference that was held this morning in Japan. Another part of the press conference regarded Ryota Murata's (7-0, 5) next bout taking place overseas and maybe Teiken are hoping to send both Murata and Miura overseas and get them fighting on the same card, possibly in the US.
