Welcome to MacRumors!
Hey you stole my bit!

(which I probably stole form someone else....err umm carry on

Anyway back to the topic...
Some people are expecting video Podcasts soon but, I have to burst this bubble. There are a lot of problems, video podcasts won't be as easy to distribute as audio ones are...even if a company sponsored the podcast (like lets say AOL) they are still giving you a lot of bandwidth to burn, costing them almost 3x more than an audio podcast.
First off although a lot of people do have a high-speed internect connect a lot of people don't. Music files are very small compared to video files. Think of this, a audio podcast is usually around 40-50mb for an hour and 15 minutes lets say, and for an example lets choose a video podcast that is usually around 150-178mb for 20 minutes or so. That's about 3x the size of an audio podcast, and it's 3x shorter too. I downloaded a T.W.I.T. (This week in tech
www.twit.tv) video podcast that was around 600mb, yeah that's a big file but, if you have a speedy connection and if you can use BitTorrent the file gets to you eventually and doesn't as long as you would think.
But, think of this, all these little home-made podcasts are say around 40-50mb, that's not so bad to upload but, even if a lot of people download the file the author could end up paying for more bandwidth, which costs a lot of money thus these little podcasts can't produce anything anymore unless they use a solution like BitTorrent, unfortunetly the iTunes Podcast section isn't like that. Seems the only way you can be on the iTunes Podcast 'store' area is host the file yourself or somehow get some big company like AOL to do it for you.
In order for video podcasts to become popular and useful I would think we would need to have some sort of way to compress the video, and maybe then even compress the file to a .tar, .rar, .zip, .sit, or whatever you perfer and then use BitTorrent to distribute the files across the web. Of course there are still problems, A) iTunes doesn't use BitTorrent or a similar way to download or transfer big files, B) users with slower connections are left out, C) Your still dealing with a big file and some people just don't want to wait that long to get a file that they might or might not be interested in.
Some people say, well who cares about the dial-up users! We don't need them! Well unfortunetly dial-up users are still a big population, and although it's not fun you can download music from the iTMS on a 56k connection - it'll take a while but, you can do it and pray you don't get disconnected. But video is totally out of the question.
So IF...if...Apple or someone else comes up with a awesome fool-proof solution and there are enough high-speed interenet users that want video podcasts the video iPod will be a reality. Or high-speed internet prices can go down tempting dial-up users to get on the high-speed band wagon thus making a bigger market. Of course I can always hope for a video iPod come out in 2 weeks but, I'm a bit skeptical as some of you can tell.
