Citing a "reliable" source, 9to5Mac notes both features are being made available for the MacBook Pro this Fall, which is expected to have a ground-up redesign that features USB-C connectivity.
This is not the first time these features have been mentioned in rumors. A KGI Securities report first suggested the OLED function keys, shown in Martin Hajek’s online renders, and said the MacBook Pro would come with Touch ID support this year. More recently, code inside macOS indicated that the fingerprint sensor would be supported in future Macs.
Nate Swanner of TNW is less convinced the OLED bar is coming, so he is still dubious. It's entirely possible Apple has a variety of features for the Pro lined up that users can scale to suit their needs.
Touch ID is a curious addition, if i's indeed coming. Apple recently made it possible for sessions to be authenticated with an Apple Watch, and Apple Pay transactions are verified via the user's iPhone. There's just very little reason Apple (the company that would rather have its users buy more of its products to take advantage of these cool features) should cobble Touch ID into a MacBook.
In addition to Touch ID and the OLED panel, the new MacBook Pro is expected to be slightly thinner than the current generation thanks to new metal injection mold-made hinges, have thinner speakers aligned on the side of the keyboard, and introduce support for USB-C. According to KGI Securities analyst Ming-Chi Kuo, the new MacBook Pro will be "the most significant upgrade ever undertaken by Apple."
It is not clear, though, when the 2016 MacBook Pro will land, but there’s evidence it's already in production. Expected this Fall, the best guess is that the Pro will be announced in October and released shortly thereafter.
