Regardless of how long Season 2 lasts, it is the stated fact that Emma is still 29 as of the events of "The Tower" that, more than anything, invalidate the idea that Season 4 as a whole BEGINS in late 2013. Unless we're willing to completely discard that particular piece of in-show information, Season 3b must begin before October 23rd, 2013 (Emma's 30th birthday).

Adam and Eddy's statement about Season 4 BEGINNING in early 2013 may have indeed been invalidated, but, if so, it's invalidated by "The Tower" moreso than it is by "Darkness on the Edge of Town".
