I'm happy to see the announcement. No, I'm not switching but I think these specs are a lot closer to what a lot of D700 owners were hoping for. At any rate, it looks to be a great camera! I look forward to see how much of an improvement it is over the 5d Mk II.
If money weren't a factor, I'd definitely get it. But then again, I'd also get a leica system, a hasselblad system, a 4x5 system..
