I feel with bundles(that are not store special's, but officials) They are only good for the few weeks before(preorders) and the first week the game is actually out. Now COD is out the bundle is quickly dropping out of the first page. I expect the unity bundle to stay in the top 15 until its release. the 11th, and on the 16th it will drop out again. When both games are over 2 weeks old it just goes down to the core SKU battle again. The real question is will the 2 week spike be enough to offset the general ps4 sales. Thats also assuming that sony dont do something for later end in november
