Hmmm... that is the first I have heard of anyone saying there was a focus problem with the Canon 10D. I have been researching this for awhile too, even reading the Nikon d100 user reviews where people compared the two and many Nikon users profess the greatness that is the 10D. I know for sure the 10D resolves a known and well-documented focusing issue with the Canon D60.
You mentioned you use the 1D, but were considering getting a 1D as well? Assuming one of those was a typo, are you looking to buy a 1D or a 10D?
I know what you mean about the upside of shooting slide (as well as print film) in terms of color, contrast, etc.... but there are simply too many advantages to shooting digital.
I don't think Canon will be replacing the 10D for awhile... I could see a replacement coming in Spring 2005 maybe, but I dont see them replacing it in 2004, purely from an engineering perspective and the time and effort involved in analysis and development.
The 10D has many clear advantages over the D60... I used to have an article that discussed them, but I will have to dig around my files at home to find the link. I will post it when I do, but I think you will be much happier with the 10D, particularly it's significantly improved focusing abilities.
