1) No one knows what Apple will do with upcoming products, we can only guess
2) It's highly unlikely that they would put a camera on an iPod. If you want a camera combined with an iPhone, go and get an iPhone.
3) iPod updates occur in September, so you'll have to wait until then for a new touch to be released (assuming Apple follows their normal product cycle).
