Making a superzoom for a compact is easy, but for a DSLR, it's hard?

People say that interchangeable superzoom ("travel") lenses can't manage good sharpness, yet superzoom compacts do just fine in terms of sharpness. Why is that?

That is just another excuse. Once APS-C chip is getting cheaper, like I would say, someday it will going to be cheap as 2/3" , a better APS-C sized superzoom technology will be available in the future. but it's just too expensive to make it for right now.

Let's suppose that APS-C-sized sensors become as cheap as compact sensors are now.

An APS-C sensor is still going to require larger lenses for the same field of view range (basic optics) and so we are unlikely to see "pocketable" APS-C superzooms with decent maximum apertures (constant f/2.8 or better) and large focal length ranges (e.g., 18mm-300mm or more).

It is reasonable to expect APS-C compacts – if it was possible to build compact cameras around the even larger 35mm film format, it should be possible to build them around APS-C.  But it does not mean that the need to make any design tradeoffs suddenly goes away.
