My Thoughts:
D3100-
I'm excited about this! My girlfriend is growing tired of the D70, and this seems like a perfect replacement. She wants video and a big screen, I want cheap. Bingo! I'm a huge fan of the rocker switch below the dial, LOVED that on my GF1. If the sensor is the same as the NEX3/5, than that's great. That sensor kicks butt for noise on DX. Too bad the NEX lenses are total sh*t for what they are. I was never a big fan of the D3000, if this camera operates faster and the video is good, she might have one at Christmas.
85mm f/1.4-
24G, 50G, 85G, all at f/1.4. Sweet Baby Jesus that would be beautiful. It'd be like the "new holy trinity"! The 85mm f/1.8D is one of the sharpest lenses i've ever used, if this stacks up and the bokeh is rich like the 24G, it'll be in the bag. I'll have to see what that lens is going to be with my work discount
28-300VR-
I've never been a huge fan of the 18-200, and if I want an 11x zoom i'd get the Olympus 14-150 (i won an E-PL1 through work, might swap it out for an E-P1 though). Could be a fun one to rent for a weekend just for curiosities sake.
24-120 f/4 VR-
Before I started my addiction to primes, I wanted this so bad. This one falls into the same area as the 28-300. Might be fun to rent for a weekend just to see how it handles.
55-300VR-
If it's as good as the 70-300VR on DX, i'd get it with the D3100 for my girlfriend so she could shoot birds around the farm (she's gotten surprisingly close with her 18-70)
