How breasts will respond after an explantation varies based on a number of factors including initial breast size and amount of stretch the current implants created, inherent quality of the breast tissue and skin, starting position of the breasts prior to the augmentation, number of previous procedures. Simple explantation is typically a straight forward procedure with little recovery time. This may allow you, after about a month to six weeks, to assess your new baseline breast size/shape/position. You may be happy, or at least accepting of their appearance, or you will now have the information that you need to make the decision for a lift, with or without an implant. The incisions for a lift are a trade off for the new shape and position. Based on the pictures that you provided and those from a prior question appear to suggest a need for a lift to give you the look you hope for.
Yes, you already have some sagging and with implants removed the breast will flatten and likely sag some more.
