Are you saying you actually expect Apple, within less than 48 hours of launch, to have analysed enough customer reports to figure out what the problem might be, who is affected, work out what batches etc may be faulty, identify a solution, put that plan into place, liaise with PR and customer services, make an announcement, etc etc...?? and that's just from my very limited knowledge of how a company might go about this sort of thing.
They're not going to say anything to anyone until they know exactly what the problem is and what they're going to do about it. It is wishful thinking (to put it politely) to expect otherwise.
Also, Apple's only obligation to you is to deliver the watch within the timeframe given. Even if there was a problem, if they can resolve it and still get the watch to you within that window, they don't have to tell you squat.
