Namco-Hometek passed along some good news today,
The company has confirmed that Namco Museum Battle Collection will be published in North America this summer.
Better still, the game will ship with twice as many games than were included with the Japanese version. In all, the North American version will include 20 games–Galaga, Pac-Man, Dig Dug, Xevious, Bosconian, Mappy, Tower of Druaga, and many others.
Each game included in the collection will feature the "original" arcade mode, as well as an updated mode that allows up to four players to compete simultaneously. The disc will also support the PSP's Game Sharing mode, which means that you'll be able to "beam" any game in the collection to a friend's PSP so that they can play it until they power the system off (putting it into stand-by will not erase it).
