I wish they would, but don't think they will. Even if they viewed it as a somewhat flawed design, the next iPad was likely too far along to change something so minor.
All the debate over poor paint/anodizing, etc is irrelevant. It is a glossy surface so even an excellent manufacturing process and materials will show wear. Anything less than the hardness of glass is going to show hairline scratches and even that can eventually become marred. I think the chamfered edge should have been narrower, if there at all, in order to minimize how noticeable wear could be.
