Here's everything we know about Apple's next MacBook Pro (AAPL)

Apple just sent around invitations to an event occurring on October 27, and rumor has it's for new Macs announcements.

About time, too, because the MacBook Pro as we know it has barely changed since it was released in 2009, save for a slimmer design, spec updates, and a sharper Retina display.

Based on a slew of leaks and rumors in the last few months, we might be seeing an all-new MacBook Pro with a new look and new features. Check it out:

There will be two main models with different screen sizes.

The often reliable and accurate analyst Ming Chi Kuo from KGI Securities predicts that Apple will release two sizes of the MacBook Pro, with 13-inch and 15-inch screens.

It'll have a new design.

A report from Bloomberg's Mark Gurman claims the new MacBook Pros will have some subtle design changes, like "shallower curves around the edges," which could give them a sleeker and sharper design.

They'll be even thinner than the current MacBook Pro lineup.

Kuo believes the new MacBook Pros will have an even thinner design than the current crop.

To help make the new MacBook Pros thinner, Apple is reportedly designing new hinges to save space, according to the Chinese news site Commercial Times.
