I seriously doubt this, the reason is simple:
The previous years, we have reached a point where despite a lot of downward pressure from miners and shops constantly selling of bitcoins the price remained stable, because investors bought enough Bitcoin to absorb supply.
Now with the halving, miners will sell only half of what they used to, and although the amount of shops increases, the amount of people using Bitcoin will increase as well, so that should account for much downward pressure anymore. The downward pressure will therefore be much lower, while the upward pressure will be at least the same, if not higher, therefore the new price level will be higher than it is today.
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.
think also about total market cap. Growing it ten times would mean there is much more demand or the scope of application of Bitcoin has increased drastically in comparison to what we have now. Do you see that coming in less than one year? I, personally, doubt it very much.
