You might have to pay a lot more for your Netflix subscription if your account is regularly used on more than two devices.

A new leak reveals Netflix could be planning to limit its Premium tier to allow just two devices to stream content simultaneously. Users would have to pay around $20 a more for a new Ultra plan to continue streaming on up to four.

Netflix might be one of the best deals in the entertainment industry. For less than $14 a month, you can enjoy all the movies and TV shows you like, in Ultra HD, on up to four devices simultaneously. But that deal could be changing.

Tutto Android has obtained leaked Netflix promotional material that suggests the Netflix Premium tier is changing.

You may have to pay extra for 4 Netflix streams

The material suggests that Netflix will cut the number of available streams on its Premium plan from four to two. To continue streaming on four devices, you’ll need to upgrade to the Ultra plan.

In Europe, the Ultra plan is expected to cost €16.99 a month, which is roughly $20. That’s an extra $6 a month for exactly the same plan many of us already subscribe to for $14 a month.

But don’t panic just yet.

Netflix won’t confirm anything yet

Netflix has all but confirmed this promotional material is geniune. But in a statement to CNET, it explains that it tests different price points “continuously,” and doesn’t always make them permanent.

“We continuously test new things at Netflix and these tests typically vary in length of time,” said Netflix spokeswoman Smita Saran. “In this case, we are testing slightly different price points and features to better understand how customers value Netflix.”

Not all Netflix subscribers will see the test, Saran added, and Netflix may never offer these price points permanently.

Netflix increased prices last October, when its Standard and Premium plans were hiked $1 and $2, respectively. It seems unlikely we’d see another hike so soon, especially such a big one.
