From what we've been informed it sounds like issues regarding time and logistics made the show impossible to manage from Top Rank's point of view with the organisation said to have never come close to really making the show a reality.
In reality we feel that Top Rank have been somewhat disingenuous with the whole project which has been rumoured since very early this year and show more than a sign of echoing a similar card from last year.
In 2013 there was a set date for a Singapore show feature a number of Filipino fighters. This time there was no set date but Ryota Murata had had his name linked with the show from very early in the year signalling that "time" wasn't as big an issue as perhaps one would think. We also understand, from a Korean press release, that several Koreans were being spoken to about appearing on the card as late as mid June and that ESPN were also talking about the card in June.
We won't go as far as to say Arum and Top Rank have been misleading the fighters and fans but we will suggest that the next time there is a rumour about Singapore and Top Rank we all take it with a grain of salt, much like a Mike Tyson comeback.
We have however been informed that Top Rank will be holding another 2 Asian shows by the end of the year. One of those will be the well documented Macau card on November 22nd with Manny Pacquiao headlining the card against Chris Algieri. The other is a card in Shanghai on August 26th. From what we've heard this card will feature IK Yang in action and a WBA interim Light Flyweight title fight between Randy Petalcorin and Wisanu Kokietgym, though we are awaiting for the official confirmation the full details of the show.
