Do we still need a TC?

A teleconverter works by magnifying the image that it gets from the primary lens. You could get the same effect by simply cropping, but the assumption is that the magnified image will be higher in quality than the cropped image. For a high-quality primary lens coupled with a decent teleconverter this has been the case until now. But with the introduction of the K-3 at 24MP with no anti-alias, have we reached the point where cropping can do just as good a job?

I'd love to hear from someone with both the K-3 and a decent TC to do a direct comparison.
