It will of course find a new equilibrium sometime, and it will probable overshoot first, than slowly go down until it hits the equilibrium price. But I wouldn't be surprised if the new base price would settle somewhere around $1800. Overshooting to $3000 or $5000 isn't unlikely at all.
If anything above estimations are most likely too cautious even.
$1800 could be the top of this bull run. Then it might drop again to $900 or lower as it did before. If this bull runs slowly, it might not drop below $900.
