According to this previously posted story from Feb 22, 2013, towers 3 and 4 were scheduled to stat in April or May, 2013 - http://thechronicleherald.ca/busines...-of-next-phase
. At the time of the story, the Keelson was sold out and the Anchorage was said to be 55% sold.
According to my count, the Anchorage now has 42 of 84 units remaining (50% sold). So they haven't sold many units since Feb 22, 2013 (actually the % sold is less now than in the story). The largest number of units remaining are in the $400K and higher price category (30 of 45 units in this price range remain unsold). source - http://www.kingswharf.ca/index.php/own/the-anchorage
On the positive side, about 55% (39 of 71 units) of the units in the 4th tower (Aqua Vista) are sold (source: http://www.kingswharf.ca/index.php/own/the-aqua-vista
). So I hope that construction will soon start on towers 3 and 4.
There are still no details posted on the 3rd tower, which doesn't have a name yet - just building C.
