Is the facelift coming?

I will probably separate myself from my Q7 and look for an adequate replacement for the next 24 months (until the new Quh is there). To choose from are A6 or A7. Both are configured and could be ordered. Now, however, the question arises for me whether the A7 does not get a facelift soon. From the age, according to experience A6, A4 the 3 years would fit and I want to prevent getting a vehicle which is already overtaken a few weeks later. So in the A6 rather unlikely the A7 But I still like it better, there is no significant difference from the price. What do you mean? Has anyone heard anything yet? Greetings Siegcon
