Its highly unlikely for them to put such a suspension in this truck for the sole reason of its probable price bracket. Such systems are typically only found in the highest end trims on SUV's/trucks. While I certainly understand why you'd want it, those who decide to outfit their Blazer for off-roading are more likely to get something aftermarket anyways. I don't see the new Blazer as having a very off road capable design to begin with.
