Wouldn't be surprised if there is no facelift, straight to the MK8 (which is likely to be a facelift in all but name, like the MK6 was to the MK5). The "new" A3 was out about 8 months before the MK7 Golf, so if the updated A3 is due in May/June 2016, very early 2017 could well see the MK8 Golf. Seems daft to me to facelift a car and then replace it around a year later. The MK5 only lasted 5 years and the MK6 only lasted 4 years, the MK7 will be 4 years old this Autumn.
