I guess what you are saying is that there will possibly be a firmware hack for the DSLR, it's just that it is not the CHDK and it won't be called "CHDK". Right?
Obviously the abbreviation CHDK would suit any Canon DSLR hack just as well as it does for these point&shoots, but the way we know and love CHDK is a SVN repository with nightly builds for Canon point&shoots built around Digic II/III/IV. There's no sense in attempting to add DSLR stuff in the CHDK source tree since the two product groups have so little in common. We aren't adding i-pod hacks in the CHDK source tree either...
None of this means DSLRs couldn't be hacked in every which way you can possibly think of. It's a matter of finding eager developers that don't mind bricking a DSLR or two to find out what they can achieve. Some things have already been demonstrated as you can find in the dslr hacking section.
