I believe most Mac laptops are limited to 24/96, but I could be wrong. It would strike me as very odd if a MBP was less capable at anything than a MBA given the Air is designed to be über portable while the Pro is the flagship. I can alway ask my boss tomorrow to confirm with the Pro Retina, however.
The only reason I think it might go to 32/96 is because my iMac, which is a couple generations back at this point, does 32/96 so I wouldn't be all that surprised to find it was in the pro as well.
Either way, 24/96 should be pretty much enough unless you're expecting to spend more than the price of a MBPr again on audio gear in the form of a DAC, amp and epic headphones.
