There's no reason not to believe him. Why would he lie? Most people don't have a reason to have a 60 GB iPod. The people that have 60+ GB of music either has been collecting music on CDs for a quite a while, or most likely they stole most of their music anyways.
There's no need for video out or anything else like that. The iPod is a simple device designed to do a very simple thing, and thats store/play your music. Its not made to view videos, or look at photos. Sure, Apple has made it so that it can do some other simple things, like store your photos, play audio books, and record voice, but those are simple little things that don't require adding another button, or port which would further complicate the device.
When Joz says not anytime soon then I don't think you'll see it for quite a while. I'd say sometime next year. I'd say this is the last iPod update for this year. Other will think I'm wrong, but they're just hoping that Apple updates them again. In my opinion, Apple spends too much time on it and needs to start focusing back on its main income, which is its computers. He didn't lie about the PowerBook G5 and he didn't lie about some other things either. So there's no reason to even think about doubting him.
