Maybe the missing “Pro” features are waiting for Lion and new Mac Pros with Thunderbolt(for hardware I/O).
Therefore Apple marketing think: everyone will have to buy a new Mac Pro anyway, so they can keep their current Mac Pro running Snow Leopard for FCP7.
It’s a way to guarantee new Mac Pro sales…
Just a thought
