Actually, it is technically not even confirmed that Killian will propose to Emma, yet.

The only real confirmation of any CS action that I recall seeing is that Killing is going to ask David for permission to marry Emma. However, I would agree that that conversation, combined with the image of a ring that was shown in the trailer for the back half of the season does strongly imply that Killian will indeed pop the question sometime before the end of the season.

I would be surprised, though, if they pulled off the wedding before the end of season 6. Honestly, if it were me, I would put Emma's wedding as part of the Series Finale as a tie back to the wedding of Snow and David in the Pilot. This would make a great bookend (in my opinioin). and to add just a touch of irony, have Regina be the Maid (or would it be Matron) of Honor.
