i really dont know what people see in psx digimon world... it was terrible overall.
annoying bowel movements, weird training, you couldnt finish the damn game on the german version due to a bug.
looked terrible too and sounded that way.
personally, i liked dusk on the ds, it looked nice and played well. once you get the hang out of typeexp and deevolution and such, it was quite fun to get great digimon and stuff.
i expect there do be digimon games on 3ds eventually, but looking at the games so far, theres just no way to expect what we get in the end
