Most will say never, just like BTC would never go below $250$ or $200.
Hint: They are releasing more coins as we speak.
So with 31billion counted on the site, autobridging, and a nice press release soon, I am going with February 2015.
It doesn't take much if BTC goes to double digits and XRP goes up.
Again, Bitcoin was an idea for the people to grow upon it. Let ripple be complementary to Bitcoin and be a safe place to hold and convert as well.
So what's your guess?
