As late as possible.
I'd rather
(a) not have Larian run short of money and find themselves forced to ship the game, and
(b) that Larian takes the time to address the numerous issues the current version has, many of which are with very basic things (UI, controls, etc) which have nothing to do with vision.
The second point is a matter of will, which will be what it will be, so let's hope they don't find themselves forced to ship to pay bills and salaries.
