I think that big dump at the whole market is possible in few days or weeks. May be when BTC correction will happen many investors and traders will move their funds to bitcoin gold as well as bitcoin cash... who knows.
Correction in the bitcoin ecosystem is done already. It is almost $10K again. I don't think that investors are moving their funds to bitcoin gold. The last correction in bitcoin market was due to the fact that people are just cashing it out and not moving their funds somewhere else. This is evident because altcoins didn't gain when bitcoin went down a 2x in couple of days.
I'm sure that bitcoin gold could be pump and pump hard, but not this time. Wrong timing to pump it because all money are into bitcoin market right now. Maybe before Christmas we will see some pump, but I could be wrong.
