You could probably find out aproximatly how big it is if you really wanted to, by using the map on PT and seeing how big the villages are compared to the villages in VV1 and 2. Then you could find out the area of them and then find how many go into the map.
I'm not sure if that'd work but it was my only idea.

Another possibility is that all 3 games were originally independent of each other, but they liked the name Isola so much, they used it more than once. And they already had the graphics for the villagers so why not use that again, as well.

But the games are played by the same people so much that they'll find a way to tie them all together in the future.

Just guessing! If they did write each game with a master plan to tie them all together, that would be a very long term plan from the very inception of the games!

Well, how could VV2 have been independent? I mean, you're still on the same island... All three of them are on Isola!

I think Vicki was talking about PT, FT, and the VV games

I do believe that FT and PT are spoofs of VV, in that order.
[VV1, FT, VV2, PT, VV3]

I timed one of my villagers going from one corner to the other and estimated that it took him one minute.

In Villagian Time (anyone remember my old calendar?):
on Slow: takes 1 day to get across
on Normal: takes 3 days to get across
on 2x: takes 6 days to get across

Hmmm, no wonder time seems to fly by when your collecting coconuts!!

If your pattern is true, HP, would that mean there is another spoof coming up?

I have no idea!!
I suppose they could. Many people have suggested other tycoons that would be related to Isola. If LDW makes it, I'll buy it!
