I bought my copy off of EBAY, but one of the GM's said it was still available, but I have heard some contradictory reports from both the Amazon, and other players that have purchased have recent copies of the game, but Ebay has them for super reasonable.
I got my Amazon Borg BO last month. It was being sold by Amazon not a Marketplace seller. The was a sticker on the box indicating the Borg BO was included. My buddy purchased a copy from Amazon a little over 2 weeks ago at it was still included.
On a side note I think it's a good purchase for those needing a copy after their ability to play on a referral key expires.
