I really hate to speculate because I don't know the true specs of the Focusrite. As far as I can tell from their site, the only place where 192kHz is mentioned is on the SPDIF, not the analog or ADAT inputs. I would give them a call to confirm this.
In regards to the Firestudio:
You only have a max of 96kHz sampling rate. However, you can do 18 inputs at 96kHz and 26 inputs at 44 or 48. You also have the ability with the MSR remote to add talkback, speaker switching, surround control plus a total of 2 additional headphone amps, all of which can have separate mixes coming from the computer. In total, you can do 9 stereo mixes on the Firestudio and route those to any of the physical outputs all with no latency.
The other major feature on the Firestudio is the new clocking circuitry called Jet PLL. It is an amazingly low jitter clock (Below 300 picoseconds of jitter) and sounds amazing.
We'll have full specs and videos on the Firestudio that will go on our site in about 2 weeks.
Hope this helps.
