PHOTOS of New MacBook Pro Disappoint

News that Apple’s (NASDAQ:AAPL) MacBook Pro line won’t get quite the makeover that had been hoped for doesn’t seem to have dampened the mood ahead of the annual Worldwide Developers Conference, which kicks off today — at least, not for investors. Apple shares were up 1.25 percent less than an hour before the conference was scheduled to begin with a keynote address by CEO Tim Cook.

But maybe investors should be a bit wary, as purportedly leaked internal components suggest Apple has plans for a new chassis nearly identical to that of existing models, which means the new MacBook Pro line might not be getting the refresh most Apple users have been hoping it would.

Images shared on Chinese forum WeiPhone (see below) supposedly show the new NVIDIA (NASDAQ:NVDA) GeForce 650M Kepler GPU and graphics memory indicate a mainboard design that matches up with the screwholes and shape of a current generation MacBook pro mainboard. That also suggests the mounting options inside of the new notebooks are the same between generations, rather than the 2012 model having a dramatically different aesthetic.

Earlier rumors suggested Apple’s new Pro line would resemble that of the MacBook Air in style, ditching the bulky optical drive so as to save space and allow them to slim down the new notebook.

However, SlashGear does suggest that the leaked images may only be of an Apple test board, trying out NVIDIA’s Kepler GPU with OS X and intended for only Apple’s engineers, and not for actual release. SlashGear also suggests, if keeping the old size and design, Apple could still be removing the MacBook Pro’s optical drive, freeing up room to accommodate a second HDD/SSD or bigger battery.

Apple enthusiasts won’t have to wait long, as WWDC kicks off today with a keynote scheduled for 10 a.m. PDT (that’s 1 p.m. EDT). The WWDC keynote is one of Apple’s major product launch platforms. Wall St. Cheat Sheet will be covering the conference and major developments.
