According to Curbed Boston, there are 4 new developments that are oohh! worthy. The winner is the new Boston East Complex in East Boston with 200 units right on the water.
Runners up are Lovejoy Wharf in Charlestown, The Harlo near Fenway (my personal favorite), and The Lucas in the South End, 33 luxury condos.
