It was rated by the ESRB in late 2009, but SNK hasn't said if it was coming stateside since (It was also at one point slated for release on the PS2, but those plans appear to be dead).
Given the state the PSP is in at this time in North America and the long gestation period for this title, this looks to be something everyone can count on not coming stateside. But with the import friendly nature of both the PSP itself and the included content, it shouldn't be much of a problem for anyone that is interested.
It's developed by G1M2, known for some of the better recieved SNK compilations of years gone by. Here is the case insert, a trailer, and the game list.
Included games:
Ikari Warriors (1986)
Dogosoken (1986)
Ikari III: The Rescue (overseas version) (1989)
Athena (1986)
Psycho Soldier (1987)
Sasuke vs. Commander (1980)
TANK (1985)
ASO (1985)
Prehistoric Isle in 1930 (1989)
Bermuda Triangle (1987)
Vanguard 2 (1984)
HAL 21 (1985)
Marvin’s Maze (1983)
Guerrilla War (1987)
P.O.W. (1988)
Street Smart (1989)
SAR Search and Rescue (1989)
Touchdown Fever (1987)
Gold Medalist (1988)
Super Championship Baseball (overseas version) (1989)

Nice to finally see some attention given to the real gems of SNK's library of classics. I just wish there hadn't been licensing issues with Vanguard's audio. I'd of loved to finally have gotten a proper arcade port of that at long last.
