Nikon D7000 or D300 or D300s???

[smallfooties]

Hi all,
Just wondering, what's the natural progression from the D200?
I shoot mainly street, abstract, macro and some landscapes. Would like to be able to produce clear images in low light or night time. And i think being able to produce good low light images are a necessity for me now that i only have the evenings to do photography.
Yet, i don't want something with the video fxn or something with the flip screen...
Any recommendations will be appreciated. Thank yous!
PS: i'm not thinking of upgrading anytime soon... but would like to have the suggestions when i do want to upgrade.
