Argh... I should check these forums more regularly!
I have to give credit to the OP for seeing what's right... although it might be unrealistic given the financial circumstances. And as others have suggested, with the current method, we can at least evaluate how a lens performs relative to other lenses that we're familiar with.

Beyond 10mp (APS-C) and 20mp (full format) an camera upgrade has more to do with "political correctness" rather than sense.

Don't mind if I comment on this... while it may not be possible to get any more detail out of the lenses on sensors with more pixels than the ones you mentioned, higher resolution Bayer sensors do reduce the spatial size of the digital noise and demosaicing artifacts, for a fixed reproduction magnification (not 100% viewing on the screen).
Of course, I don't mean simply increasing the megapixel count without improving the efficiency of the sensors is good. Particularly, the fill factor shouldn't be decreased to accommodate the extra pixels. But recently we've been seeing improvements in this department, with the help of Canon's gapless micro lenses, etc.
