delay Rockman Zero Collection to an unspecified release date (originally slated to release April 22). However, rumor has it that Amazon Japan is sending out an invoice to Zero Collection customers that the game will ship May 27. Amazon's page for the game, however, still shows the release as TBA.
The reason for the delay in the first place wasn't divulged into, but a note over at the game's official website alludes to "developmental issues." Some fans speculate the delay might be due to the developers opting to add additional features to the game, or perhaps they've run into some struggles.
In any case, I've marked this one as a rumor until Capcom officially announces the new release date. Thanks to reader ShinNeo for the tip.
