We probably need a lot more information.  If they simply take existing transfers and put them on Blu_ray at a higher resolution, yes, they will look better -- the same way any black-and-white film looks better on TCM's high def channel -- but that's not quite the same as a restoration, which includes careful cleaning of frames, enhancement and even restored footage.

I doubt very much that any new or found footage will be included, so it becomes a matter of how well they can get the best source materials. BRIDE, especially, is in need of a real improvement. Some of the existing DVD versions are out of frame (the cross in the hermit scene can barely be seen where in other versions it is lower in the frame, etc.).

But yes, here's hoping...
