As discussed elsewhere, Stern are releasing a lite version of BDK, with a few of the main toys eliminated, selling at Costco at $700 less than the standard version  I could understand if it was a decent saving but if you are going to pay $3300 USD for a game, I think i'd pay an extra $700 for the real version.  Maybe if Stern were selling it at half the original price then I could understand.

Anyway here is the review:
