Capcom’s Christian Svensson recently commented on the possible re-releases for three of their classic fighting games for the Playstation Network. When a fan asked for an update about Cyberbots: Fullmetal Madness, Darkstalkers: The Night Warriors and Star Gladiator possibly becoming PSOne Classics, the Corporate Officer and Senior Vice-President responded with the following statement on the Capcom-Unity forum:
Two of the three of those will happen at some point in the future... timing however is solely dependent upon SCEA. Not under our control.
Earlier in the same thread, a mod revealed that Christian Svensson “is still fighting for a Western release of Cyberbots.” First released in 1995 for arcades, the console version of the mecha fighting title was never released in North America.

So it appears that Darkstalkers: The Night Warriors and Star Gladiator will be re-released on the Playstation Store for the PSP and Playstation 3 sometime in the future. Darkstalkers: The Night Warriors came out on June 6, 1996 while Star Gladiator was released on October 31 of the same year.
