Apple accessory manufacturer Griffin has unveiled PartyDock, a new peripheral that allows up to four users to play games on a single iPad or iPhone 4 with their own wireless controllers. It's also designed as a media dock for video/photos/music and can connect to an external monitor (composite/component connections).

Griffin hasn't announced pricing or a release date for PartyDock yet, but it says it will release a PartyDock app with three free minigames (Midway Motors, Fishing Frenzy, and Flippin' Frogs) and support a Wits & Wagers Family app. Some product shots of the dock show off a Battle of the Sexes port, too.

The company says it will release more PartyDock-compatible games in the future, which consumers will be able to find by searching for "Griffin Publishing" in the App Store.
