It has a very low possibility that it will ever happen as Bitcoin as basing on its price history you will see that when it was on the 3000$ level it never got down to the price of 1000$ again. Obviously if Bitcoin will decrease more than 50% of where it is now we will know that something is up and there is really a bad news that made it to where it is now. Looking at its price charts now you will see that Bitcoin is still on a up trend that is why I don't know why you are thinking that it will correct on that kind of level.
Exactly,the possibility of seeing the price on that scale is already very remote,that there was a backward movement so marked it would not be very logical,instead, it is much more likely to continue giving a slight and gradual increase as it continues to popularize its use in different areas or activities that people have or do as investments or things like that through BTC, in the other hand, is very possible that the new floor is already established and a new evolutionary process will emerge from this.
