I've been eyeing the 10D for a while and just saw the digital Rebel out the past few days. I'm waiting for several reasons:
1. Don't really need the camera until middle of next year
2. Price will probably keep dropping
3. Capture area of the Canon digital SLRs (unless you go for the very pricey EOS 1D) is limited so lenses are all multiplied by a factor of .6 so a 20-100mm lense for example is effectively a 32-160. Cheap telephoto but not good for wideangle.
4. Trying to avoid/minimise paying sales tax so I want to buy it when I am down in the U.S. and have a C$750 duty-free exemption for Canada.
The Eos Rebel comes with a lense for that price (10D is body only) but the range is limited.
