David Wise, writer of many of the best episodes of the G1 cartoon (including "The Key to Vector Sigma" and "War Dawn") and main writer for the original Teenage Mutant Ninja Turltes cartoon has
announced on his blog that he's going to be writing an episode of Big Finish's "Gallifrey" miniseries.
This is for an audio-drama spinoff rather than the main TV series, but it still sounds pretty cool and will be featuring the voices of quite a few major actors from the original Doctor Who series.
