Big Ant don't really do sales. I had their Rugby League game on my wishlist for ages, but eventually gave up and took it off after about two years.
They did have a sale for DBC2014, once. When the Aussies toured England a couple years back Shane "Leg Before" Watson was out LBW in the first innings of a test and they said if Watson got out LBW again in the second innings they'd put the game on sale.
Maybe if the Aussie players do actually go on strike during the upcoming Ashes they'll put DBC17 on sale to make up for that, but I wouldn't hold my breath.
