Apple To Do Handheld Gaming?

The Apple intertubes are all abuzz about news that Apple has filed an extension to their trademark to handheld gaming devices, specifically:

Toys, games and playthings, namely, hand-held units for playing electronic games; hand-held units for playing video games; stand alone video game machines; electronic games other than those adapted for use with television receivers only; LCD game machines; electronic educational game machines; toys, namely battery-powered computer games.

Is this just to cover the iPod gaming, or is there more afoot? Some may remember Apple's past failed attempt at the video game market, the PiPP!N.
