After reading all of the posts so far, perhaps the question should have been:

Why are Canon APS-C sensors getting smaller?

Here are the sizes that Canon has produced:

  • 22.7x15.1mm: D30, D60, 10D, DR/300D

  • 22.5x15mm: 20D, 30D

  • 22.2x14.8mm: XT/350D, XTi/400D, XSi/450D

  • 22.3x14.9mm: T1i/500D, T2i/550D, T3i/600D, 40D, 50D, 60D, 7D

The "why" of modern Canon APS-C DSLRs having slightly smaller sensors than their early ones has already been explained in this thread. It's image-circle problems from some EF-S lenses, particularly the 17-85 IS.

Modern Canon APS-C sensors are only 3% smaller than the early ones. The difference is truly insignificant.
