There will certainly be more clues to the earlier inhabitants of Isola since VV2 has continued the theme of unearthing lost artifacts and remains left behind by them. Since we've now settled two parts of Isola in VV1 and VV2, there will probably be another two so all four quarters will eventually be explored. If the mystery of the earlier inhabitants is not solved in VV4, then maybe the villagers will master the art of boatbuilding and sail off to a neighbouring island to try and find them.

I'd like to see chickens (the kids could collect eggs to boost the food supply) and maybe goats (several possibilities there). Larger animals such as cows and horses need a lot of grass and space and don't thrive on tropical islands.

I'd also like to see a village gathering every so often with the villagers dressing up in special costumes and maybe some of the other villagers playing drums and flutes. Maybe two new skills in VV3 could be "Musician" and "Dancer".
