I'm sure this will lead to another couple of price increases between now and 2016. Oh joy.
No. The price is going to stay the same forever.

Honestly, Netflix people are really damn spoiled. Yes, the price will go up at some point, deal with it. Even if the price was $20 a month it's still better than cable and 90% cheaper.
You want streaming all in one place with original shows? You have to pay for it. I'm sure by then the price will go up to $10, but not anytime soon because other companies are trying to bring Netflix down.
