I'd say right on the speculation line. It's far-fetched to say he can totally see, but he may very well experience some limited optical sensation, albeit one of such limited utility that we can't really call it sight.

The story about him seeing Shaq is an interesting example. If you already know that Shaq lives in your apartment building, how much visual acuity do you need to make an educated guess that the large form waiting for the elevator is probably Shaq? There's also no one to tell us if he ever stood there talking to thin air thinking it might be Shaq ;)

It also seems like the kind of thing that would be difficult to give a satisfactory description of, so being coy about it is probably for the best.
