Nobody knows the exact or even orientative value of Bitcoin. As of now, it's gaining momentum, and it's just reaching the well informed masses.
I barely paid atention to Bitcoin in the past, altough I did read a lot about it, I thought it wasn't the coin that would explode. I was waiting for another coin. But it has exploded. Nobody can ignore Bitcoin now, and the supply is limited. 10k$? certainly possible. Wait until big online shops accept it, and it will gain even more momentum.
There are a lot of people interested in the success of Bitcoins beyond current Bitcoin owners. From anti-Centralized Bank printed money, to big nations contrary to the status quo.
Yeah, I expect it to explode even more and go over 10k$
