That's coming, but your budget will dictate. Thunderbolt devices will allow you to do this with ultra-low latency in your DAW, but that tech is not going to be widely available until 2014. Trust me, all of the major mfg companies will offer this tech soon, so be patient. What's cool about Thunderbolt buses and peripherals is that you can daisy chain up to six devices for one port. You can use a MacBook Pro with Thunderbolt and use 6 daisy chained 8 channel, or smaller audio interfaces if needed, or a smaller audio interface and go portable. Again, all of this at Ultra-low latency.

Here's Chief Hardware Engineer Bob Bauman with Lynx Studio Technology talking at length about the benefits of Thunderbolt buses for use with audio peripherals.
