It could be that their renewed license for the IMVE run a few years back is about to expire. So, they probably plan to burn through excess parts and beat the wire. If it's only a few hundred games, that's probably less than a week on their assembly line. I doubt a rerelease of IMVE is some nefarious assembly line saver due to poor sales of other games. If current game sales are lagging and Stern needed to go through the trouble to renew a license to release a vault and plug a substantial assembly line hole, why not pop out a game with more sales upside?
