You don't have to be rude.
And besides, we're in the iPod Touch forum section, not the iPhone forum section.

I don't think they'd add videos to the iTunes Wi-Fi Music Store because after all, it's only called the iTunes Wi-Fi Music Store.
It's purpose is mainly for you (or anyone) to get music whenever, wherever on-the-go but only for the convenience that you get it without having to do it on he computer.
And because it's also used by iPhone users, I'm guessing videos weren't put up on the stores because they didn't want the wireless networks getting all jammed up with downloads. Alas, specifically, the iTunes Wi-Fi Music Store.
