I suspect they will be optically superior if they come to pass. AFAIK the Celestron Edge uses a spherical mirror with with a correction lens. The Canon patent distinctly shows and aspheric mirror design which should be inherently superior. In the end, it is all in the implementation, but the odds are very high that Canon will do a better job. The patent also shows a considerably more complex lens grouping than any of the conventional telescopes. Some of that will no doubt be due to the IS, but I suspect more care in correction as well.I wonder how these Canon lenses would compare with the equivalent telescopes. The Celestron Edge line of scopes (see here) would be one of the competitors. One big difference would be the mounting assembly. Telescopes typically come with dovetail bars to attach to astro mounts rather than tripods.
