A lot of it will depend on if I can find someone willing to do some cross system trading. As I told you quite a while ago switching to Canon was a major pain, switching back to Nikon is going to be an even bigger pain because I have a lot more glass. Also, I'm sure the recent/current lenses will be fine at that resolution but I want to wait and see about earlier lenses.
One more thing - the new Tamron 24-70 VC may change things a bit too. Tamron has really been improving and that new lens looks promising.
I did some reading on that lens too. It definitely looks promising. 
Switching now




It's going to be pricey!
Nikon glass is a little bit more expensive as well. Then again, I've been eying the Sigma 85... It's pretty dern sharp!
