I think that was kinda the point when they released DOA: Ultimate.
I know everyone here only cares about 3.1 (which admittedly would be awesome to have released in the US for 360/PS3), but man, I'd love to get DOA2 back on PS3. Especially Ultimate, but the original is great, too. It's the game that first got me hooked to DOA, and there's so much great content in terms of arenas, costumes, music, etc. that aren't quite captured in any of the other games.
I'd nostalgia my brains out for an HD collection with 3.1 and 2/2:U.
