This 1UP report contains a quote from Microsoft admitting that not all those who pre-ordered Banjo Kazooie: Nuts & Bolts received their code to get the original Banjo from XBLA, as well as a note saying the game's release has now been delayed until December 3.
"We are aware that some consumers who preordered Banjo-Kazooie: Nuts & Bolts have not received their redeem code for Banjo-Kazooie on Xbox Live Arcade," said the firm in a statement.
"We are currently investigating the scope of this situation, but we believe it represents a small fraction of the total number of preorder customers. We encourage anyone who preordered Banjo-Kazooie: Nuts & Bolts and did not receive a redeem code to follow up directly with your retailer's customer service team for resolution."
Despite the delay, pre-orderers will still get the XBLA game a week earlier than everyone else, Microsoft's assured.
