I personally run the events to win the cars I am short first then run the others just for the gold rewards I may net on the ones for cars I already have. I dont think this will be an issue. While some have said, they have overlapped updates before, I think their memory is flawed.

I do not  remember them ever doing this. There is always a date that is the last date to enter an event, then you have so many days to complete. If my memory serves me correctly, the new update will not come out until that event is come and gone.

So if the post above is correct, that the Fandom User still has 5 days to go on the a flashback event, I would guess we have at least 5 days until the update. JMO
