Heres my toughts:
Ikonoskop - expensive (worst bang for your buck), small amount of features/big price, heard it has some WB issues
Panasonic AF100A - yes its old, better cameras available
Red One - its old, many hardware and software issues, any do you remember its Red Digital /Cinema/ Camera
Sony FS700 - all around awesome camera (slow mo, upgrade path...)
Sony FS100 - still good if you dont have money to spend on FS700
BMCC - not suited for doc work (again Blackmagic /Cinema/ Camera). and to me that camera still looks videoish (dont rage on me, its my opinion) much better than other but still...
best bet go with Sony (good mount,good low light, slowmo, upgrade path...)
maybe you want to wait for NAB and then see
Cheers!
