New evidence surfaced recently again suggesting that Apple is working on a new 13-inch MacBook Pro. The evidence follows a trail of rumors and reports suggesting that Apple may show the device as early as next Monday during WWDC 2016.

The latest is a rumor from China that suggests Apple supplier Jarllytec recently reported a boost in sales thanks to an order from Apple for new 13-inch hinges. DigiTimes, citing Commercial Times, said that the hinges are bound for a new 13-inch MacBook Pro that will “begin shipping during the third quarter of 2016.” Given that it’s the end of the second quarter, that fits nicely with reports that a MacBook Pro 2016 is about to debut.

The metal injection hinges (MIM) are easier to manufacture, DigitalTrends, said, which suggests Apple’s manufacturing partners may be able to build more of them even more efficiently. It’s unclear what sort of benefits consumers might see from these changes, if any.

The new MacBook Pro 2016 is also supposed to pack an OLED display above the number keys that’s capable of morphing to show either F-keys, additional controls inside applications and even Siri. You can see the concept above for a closer look at how it might operate.

WWDC 2016 begins on Monday, June 13 when we expect to hear more on the new MacBook Pro 2016.
