Pure speculation on my part, but I think we are entering a period where refresh cycles for all DSLR's will get longer. The technology is maturing and I doubt we will see the rapid advancements that occurred in the first decade of this century.
Honestly, I have a very hard time figuring out what Canon would put in a Rebel that would add value and still not infringe on the 60D.
It wouldn't surprise me to see Canon competing on the basis of pricing, rather than features, for the next year.
