I don't think it's a step backwards due to the USB vs Firewire. The Pro is using newer technology then the 410. Once the signal is digital it makes no difference what buss it travels 1's and 0's are still 1's and 0's no matter USB, Firewire,Cat6 or whatever. What would make the most difference is analog section and the A to D conversion. But really I don't think there is going to be any noticeable differences other then the cable.

Someone once posted a link to Firewire 400 vs USB benchmarks for audio and video. It showed that FW used more CPU and slower transfers when sending two way streams.
It <firewire> is preferred over the more common USB for its greater effective speed and power distribution capabilities, and because it does not need a computer host. Perhaps more important, FireWire uses all SCSI capabilities and has high sustained data transfer rates, important for audio and video editors. Benchmarks show that the sustained data transfer rates are higher for FireWire than for USB 2.0, especially on Apple Mac OS X…
Although high-speed USB 2.0 nominally runs at a higher signaling rate than FireWire 400, data transfers over S400 FireWire interfaces generally outperform similar transfers over USB 2.0 interfaces. Typical USB PC-hosts rarely exceed sustained transfers of 280 Mbit/s, with 240 Mbit/s being more typical. This is likely due to USB's reliance on the host-processor to manage low-level USB protocol, whereas FireWire delegates the same tasks to the interface hardware (requiring less or no CPU usage). For example, the FireWire host interface supports memory-mapped devices, which allows high-level protocols to run without loading the host CPU with interrupts and buffer-copy operations. Besides throughput, other differences are that it uses simpler bus networking, provides more power over the chain, more reliable data transfer, and uses fewer CPU resources.

Not sure about the timing thing but usb interfaces can use the internal clock just like firewire.
I know manufacture have been using Firewire on higher end products so a $1300 device will be better then a $200 device. But the difference between like devices 410 vs FT Pro should not be noticeable.
And I still think firewire is better when using many devices or high end products but for most garageband users who just want to record a demo or put their songs on the net it just won't matter.

Seeing both FW and USB 2.0 can sustain speeds around 200Mbps + that shouldn't make much of a differences unless you're working with 100+ full tracks.
I still don't see how 01000011 01101101 00001101 00001010 would be any different carried over usb, FW, Cat6, optical or a flash drive.
