You can shrug off the reported AF issues on the Canon D7, I've had none and none of the other owners I know have any.
D300s has better noise levels at high iso, but this is offset somewhat by the higher resolution of the D7.
D300s video is much more limited (if that's a motivator for you), and the D7 is getting the same (fantastic) Magic Lantern firmware support that the D5mk2 gets at the moment (magiclantern.wikia.com), which is true game-changing stuff, especially if you're a capable programmer yourself.
And let's not get the price facts wrong.... the D7 is currently cheaper than the D300s by a couple hundred squid. For just 400 more than the difference, you can get a 5DMk2... full frame, even better high ISO/low noise, and the rest. Get it for even less refurbished (check out Canon's e-bay shop).
