Pit-Road 1/350 New Jersey upgrade set at Hobby Link Japan

I was just checking the HLJ site and saw a listing for an upgrade set for the 1/350th USS New Jersey. Does anyone have any idea what comes in the set?

I know the raised helipad is missing from the Tamiya kit and there are other problems with the kit but as this sset will cost more than the model itself I would like to know what to expect before I order.
