Vingles
With the rise of ipods and other hand-held media with video capability, "vingles" are apple's newest trend du jour. Similar to a "single" --or song released as a single-- Apple calls vingles a "bundled offer of video and its corresponding single" according to yahoo news.
Offered through itunes, apple expects video collections to be a growing trend.
Since ipods with video screens are now the standard, once shuffle and other non-video-screen ipod users are in the market for a new mp3 playa', they'll likely adopt one of their fav brand's new listening devices.
Also, with the rise in popularity of google video and video podcasting, I can't see how apple's prediction will be wrong.
