Most beta testing has a life span of around 90 days. But VV2 could be a little different since LDW does not have to start from scratch. So I would envision that first beta could be "labeled" as a .70 or .80 version. If that assumption is correct, a thorough beta test could take as little as 30 days. Keep in mind it takes around 5 to 7 days to complete the present puzzles and milestones in VV “A New Home”. As well as typically with each new beta version you need to delete all files from the previous version to insure you are testing a clean version. Thereby you would have to start over with each new beta version.

This is purely speculative on my part, but it does seem logical.
