The AppleInsider describes a new trademark application by Apple. The request term "iPod Hi-Fi" suggests that the company is developing some kind of hardware or software to provide Hi-Fi support for the iPod player.
This idea is now new, and several people have commented on rumors that Apple would be creating a wireless version of the iPod. However, if the news is true, this is the first sign that Apple is really creating some kind of remote access device that has iPod-like capabilities.
In a separate news, the AppleInsider speculates about the possible announcement of iPods with larger screens:
Separately, sources said that Apple is developing an iPod model with a higher-resolution display and about an inch of additional viewing area. It's unclear if, or when, the company intends to release the device, and no further details were provided.
