Sounds like another crippled product then. Why doesn't it at least have an A8X? Apple are usually pretty good at putting future technology like ports and latest wireless standards into their products. The lack of ports and 4K support just means this is already due an update.
4K support isn't essential at this point because the vast majority of content won't be in 4K for quite some time. By that time, Apple will probably have introduced 27 other updates to their various products so I'm fairly confident they'll update the AppleTV.
