Bruce -- I'd forgotten that the "s" provided video -- 720 @ 24, compared to the 7D's 1080 @ 30 or 24, for the top respective quality levels.
I set the Kool-Aid aside to directly compare specs, and yes, the Nikon does provide moisture and dust prevention, but stops short of Canon's more pronounced claim in the line of weather sealing. Still, probably a wash.
And good as the 7D's AF is, I'll concede that Nikon's D300s might be better, even with less cross sensors. I would have to rely on those who've used both for an opinion on AF capabilities.
FPS is close with Nikon having 7, and Canon 8, so about 15% difference, not huge but could make or break the shot for fast action.
D-Lighting is cool, and 7D isn't in that league.
ISO -- Canon native 100-6400 (exp. 12,800), Nikon native 200-3200 (exp. 100 & 6400)
As we've discussed, the 7D has 18MP compared to D300s' 12.3MP, or 50% more capability.
There are other minor points that jockey back and forth, but I still don't think the improved D300 is really a direct challenge to the 7D, but it is an attempt to catch up in that direction. No doubt a new D400 would slaughter this aged 7D's stats, but it is yet to be seen what Canon's eventual upgrade will be.
As I said earlier, it is great to have these two companies duking-it-out to our benefit! And now Sony is a serious contender in DSLRs too.
