and he asked me how many megapixels my camera has
You should have answered "all of them" and then just stared at him.
The E-30 came some time after the E-3, with improved features
It was the E-5 that followed the E-30 and built on it, not the E-3
To his point though, I remember getting my E-520 and back then Olympus wasn't concerned about undercutting the flag ship camera with new features on the E-520 released 6 months later. We gained stuff like being able to turn on just horizontal or vertical image stabilization for use when panning which the E-3 didn't have and maybe a slightly larger LCD. Of course the E-3 still blew away the E-520 in most other stats. But they didn't seem to hold back incremental improvements from "lower" models when those improvements were available.
