D610 is great! They fixed the shutter oil escape problem the D600 had.

Personally I am a Canon fan. Bought an 6D and I am super happy with it. The only problem is that I took the 24-105 L which doesn't offer much magnification and only afterwards I noticed the 24-70 F4 which can reach 0.7 magnification, thus would be perfect for reviews photoshooting.

Storm chasing must be really cool! I work on a mountain and most of the winter time I encounter huge storms out there! But don't have the courage to go out and take shots
