you can still take a better shot, but your learning curve will be a lot lower. And you may lean on the camera like it's a crutch instead of using it properly.
If you don't know cameras, you'd be spending 3k to have a camera that you're only using 10% of it's abilities.
so yes, wise choice to stick with the D7000 for the time being. Besides, you'll be waiting a few months for it anyhow, so no rush
