Apple is left with just the finishing touches for the all-new 15-inch MacBook Pro, which is the result of years of research and development on ultra-beech and super-high-resolution displays. According to reliable sources who are prototyping components and cases for Apple's new laptop, the computer is currently undergoing production testing.
The new 15-inch MacBook Pro is expected to launch this summer and will feature an ultra-thin design, a stunning Retina display, and a super-fast USB 3 port.
Refreshed Design: While many believe the new 15-inch MacBook Pro will copy the design from the late-2010 / mid-2011 MacBook Air, sources close to the prototype claim that this is not true. The new 15-inch MacBook Pro is described as an ultra-thin version of the current MacBook Pro. In fact, the prototype is flat, but more reliable than the late 2008 version. It doesn't taper like the MacBook. The new 15-inch MacBook Pro loses its optical drive in order to achieve Apple's new standard for ultra-beeches. Apple has made it clear that professionals may lose the optical drive in favor of the popular Mac App Store, which serves to install the software. For the few who still need an optical drive, Apple sells the USB Superdrive.

While the new MacBook Pro isn't exactly the same as the current MacBook Air, it has an identical keyboard design with a power button on the keyboard. The current MacBook Pro has a circular aluminum power button in the upper right corner above the keyboard. The rest of the design is mostly unchanged: the charging and port connections on the sides, as well as the spacious glass Multi-Touch (similar in size to the current MacBook Pro and MacBook Air).

Currently, the prototype of the one-piece hull is undergoing pilot operation. On the case there are: a port for charging, two USB ports, two audio I / O and a battery indicator on the left side. On the right side, there are two holes for a Thunderbolt port, an SD card slot, and another USB port. Notably, these prototypes don't have enough room for Ethernet.
Introducing Mac Retina Display:

Apple will also use a Mac Retina display in the new MacBook Pro. The display is "amazing" and "definitely the most important innovation in the Mac in recent years," according to sources familiar with the prototype. When they introduced Retina Display to the 3.5-inch iPhone 4 screen in mid-2010, people were shocked at how great the screen could be. Launched the third generation iPad earlier this year with a 9.7-inch Retina display, 2048 x 1536 resolution, people were again amazed at how vibrant colors and crisp text can be. With that in mind, imagine the crisp text and beauty of the new laptop's 15-inch Retina Professional Display. Sources familiar with the software claim that the OS remains at OS X Lion 10.7.4 and Mountain Lion.
The Retina display of the new MacBook Pro has multiple Retina resolution modes, so users will be able to adjust the sharpness and dimensions to their liking.
Long-awaited "revolution": USB 3 will finally be used on the Mac:

In addition, a new addition to the MacBook Pro (and indeed to all Macs) is USB 3 SuperSpeed ports. Apple has been testing Mac computers with USB 3 ports for a long time, but it looks like the new MacBook Pro will be the first to feature a new generation USB port. According to the source, the aforementioned USB ports will be located on the left and right sides of the case. While some believe Apple is only on Thunderbolt, USB 3 will work on the new MacBook Pro in addition to Thunderbolt.
The exact release information, such as the date and prices, are still unknown. WWDC is approaching, so you can count on the appearance of these notebooks in June. Either way, with an ultra-thin design, Retina display, and new USB 3 ports, the new 15-inch MacBook Pro will be one of the most anticipated laptops of the year.
