It genuinely does look like a reasonable addition to the standard game if you've got money to burn. To be precise, it's looking like you'll need $200 to burn in the US - a full $80 more than the standard edition retails for in the region - according to retailer GameStop.
Now the question begs - would you pay $80 for two CDs, a slightly fancier turntable and a DJ stand. Hmmph.
Activision stuff is always cool until it gets tagged with a price.
