Adam and Eddy have stated that Will's story will come into greater focus during the second half of the season, and that we will be finding out exactly how/why he's in Storybrooke and what happened to him in between the present-day events of "And They Lived..." (which happened concurrently with Season 2) and the events of Season 4.

They do appear to be trying to get Emma Rigby to make an appearance or two, but even if they can't make things work out, we are still definitely going to be finding out what happened to him and Ana after they attended Alice and Cyrus' wedding in Victorian Land and then went back to Wonderland to rule as the White King and White Queen.
