News: The house that King of Fighters built has their list.
With most of these titles being announced a few days ago, SNK's list has no surprises. But for those still in the dark:
Xbox
King of Fighters Neowave
Samurai Showdown V
King of Fighters '94 Re-Bout
King of Fighters: Maximum Impact Maniax
Metal Slug 4 and 5
King of Fighters 2002/2003
PS2
Metal Slug 4 and 5
Game Boy Advance
Metal Slug 1
"In addition to the many new games premiering at the show, the SNK booth expects to have swarms of showgoers visiting the booth on Wednesday and Thursday, May 18-19 when noted SNK artist, Falcoon, will be signing limited edition posters of Mai Shiranui from THE KING OF FIGHTERS series. Falcoon, one of the winning artists in last year's Into the Pixel art competition, held at the show will be autographing a different poster each day. The signing will be from 2-4 PM on Wednesday and 10 AM-12 noon on Thursday while supplies last."
Samurai Showdown V was previously also announced for the PS2, but only the Xbox version has gotten any publicity in the leadup to E3. It appears canceled, but maybe we'll learn more at the show.
