Direct quote from JC in interview. So NQ has made their bed, and people have made plans and actions accordingly based on this promise. A wipe after this statement would be catastrophic, and could only be justified by an actual make or break situation for the entire game. And granted he is specifically talking about Alioth here, so there is some wiggle room for other parts of the game. But it would hardly be fair if players on other planets got wiped, while bases on Alioth stayed put.
