But as it states in one or two of those links, the 16Gb storgae equates to 2GB, but they could arrange a bank of 16 to create 32GB of storage. Not sure how much that would cost, but if it isn't comparable to the prices apple are paying for hard drives at the moment, there would be little point on switching to flash on their main iPod range unless they brought out a 40/80/100GB iPod video and turned the current colour screen iPods into flash.
Add a load of accessories with the videos and the 64GB iPod could be fairly close in price to a 40GB video, the 32GB cheaper and obviously the larger capacity video more expensive. That way people could then make a choice between 64GB of flash music and photo or 40GB of hard drive music, photo and video for close price points. the cheap accessories are in there just to seem like the 40GB is better value than it actually is.
