Apple has just introduced a new category labeled Catalogs to the App Store this evening. The new introduction is ahead of Apples media event tomorrow, where the Cupertino-based company is rumored to announce the iPad 3 and third-generation Apple TV.

The new category has yet to fully roll out to the App Store. Currently, it has apps like Catalog Spree, MTG Merchant, and SkyMall listed under it, but shows no results when viewing the category page. Catalogs may or may not have have some role in Apples media event taking place tomorrow

MacRumors asked the CEO of Catalog Spree about the new category, and he seems to think it may be related to tomorrows event:

Adding an app category is not something that Apple does lightly and we believe Apples decision reflects the importance of this usecase in the Apple App Store ecosystem.

Were not exactly sure what roll the Catalogs category would play in tomorrows event, but were sure to learn more soon. Apple also rolled out another App Store update this evening, introducing an updated interface for the iPad version.

Well be covering Apples media event throughout tomorrow, but in the meantime, you can read our predictions for the event.
