Lets define what we are refering to with reflections. Are we refering to the
AA filter? That's already coated within an inch of the mount already, so AR
coating may be impossible to be done effectively. If we really mean the
surface of the sensor, how do we know?

Well, for one thing, AG says so. :-)
A bit more seriously, some inductive reasoning:
1. The two DSLRs I have owned and the one P&S camera I've taken apart have
highly reflective sensor surfaces.
2. Many other people, here (as below) and elsewhere have commented the same
thing.
3. Several lens makers have made a big deal about their redesigned lens
and/or coating formulas to minimize hot spotting from this source.
4. Multi-coated lens surfaces have very subdued reflections compared to
uncoated ones.
5. Camera manufacturers eagerly promote any and all 'improvements' to their
products, regardless of how effective they may be.
6. I've not seen any announcements or marketing noise about such a
development.
Thus, I think it highly likely that they aren't yet in use.
Now why they aren't coated like lens surfaces, I don't know.
