Namco Bandai has revealed plans to bring two of its popular franchises over to the 3DS: Pac-Man Party 3D and Ace Combat 3D. That second one is, as you might expect, a working title.
No assets for either game yet, unfortunately. Pac-Man Party 3D is all about those wacky mini-games, and partying; those "pellets" have always been of questionable origin. Few details on the game, but it'll probably be along the lines of the Wii version. Single-cart multiplayer has been confirmed.
As for Ace Combat 3D, expect to find "touch-screen targeting and added control mechanics." Everything else mentioned talks about planes doing awesome things, which shouldn't be much of a surprise. In other words, these two 3DS titles exist ... okaythanksby!
