The PlayStation Network's answer to the Wii Virtual Console looks to expand beyond the Turbografx-16 library, with the addition of Neo Geo games for the PlayStation 3 and PSP sneaking out via ESRB ratings.
The Entertainment Software Ratings Board has rated a quartet of titles originally released for SNK's arcade/home console platform, the Neo Geo. The first four to be outed are Baseball Stars Professional, Alpha Mission II, League Bowling, and Super Sidekicks, perhaps not the Neo Geo classics you were hoping for, but a step in the right direction.
Hopefully, that leak portends the inclusion of other platforms, say the Sega Dreamcast and Sony's own PlayStation 2, making their way to PlayStation Stores worldwide.
Perhaps the Neo Geo Archives, following the naming convention established by Hudson's PC Engine Archives, will be announced in the coming days (or later at GDC).
