Scheduled takedown was revealed through an image leak that appeared on Twitter. The series has already disappeared from the US Virtual Console.
'Donkey Kong Country,' 'DKC 2: Diddy's Kong Quest' and 'DKC 3: Dixie Kong Double Trouble' are scheduled to disappear in EU on November 25. Prospective buyers may wish to purchase now suggests CVG.
US Wii owners have already missed their opportunity. Of course, anyone who has already purchased the titles will still have access. The reason(s) for the removal are speculative with no one theory seeming a likely truth. Theories include possible Wii U incompatibility, upcoming collection release, or Rare licensing conflict.
Bethesda recently pulled 'Doom 3' from Steam to promote 'Doom 3: BFG Edition' only to restore the listing after considerable fan ire had been voiced. Take-Two also recently pulled 'GTA: Vice City' from Steam, possibly due to a music licensing issue.
