I guess that this year and probably some more we will be seeing it testing this barrier. It might probably top another 20% more, but I don't believe that it will get anywhere near $1000
It's definitely doubtful to be honest, there is nearly no way that Bitcoin will go up $400 in 5 months and
that has never happened before to Bitcoin at all. It would be setting a new record for growth rates, and it is basically next to impossible to have something happen that has never happened before.
you can never tell about bitcoin future so it can be possible to go up and raise to $1000 even by the end of the this year.
and about your comment part that i made bold i have to say you should look at the history (charts) sometimes before giving an opinion like this:
http://www.coindesk.com/price/#2013-10-31,2013-11-30,close,bpi,USD (price rose from $200 to $1100)
*not saying the same will happen i am just pointing out your mistake
