SAN FRANCSICO ( TheStreet) -- Apple ( AAPL) investors are eagerly anticipating the new Mac hardware, which the tech giant is expected to debut at its Worldwide Developers' Conference (WWDC), which kicks off in San Francisco on Monday.

"Like most people, I'm looking for Apple to announce new stuff," explained Scott Grannis, who writes the Calafia Beach Pundit blog, in an email to TheStreet. "I think they will very likely be showing new models of laptops and desktops, as these are long overdue."
Apple kicks off its Worldwide Developers' Conference on Monday.

There have been rumors that Apple may launch a new 15-inch MacBook Pro featuring the HD retina display technology found on the latest iPad. This may also feature a design similar to the MacBook Air, and sport no optical drive.

Pre-WWDC chatter also suggests that the MacBook Air, iMac, Mac mini and Mac Pro may be upgraded with Intel's ( INTC) Ivy Bridge processor, bringing improved performance and enhanced graphics.

"I'm very interested in the new laptops, since I'm ready to upgrade my own which is now over 2 years old," noted Grannis. "I suspect they will be well received, being much lighter and faster, and sporting retina displays."

Retina display is one of the key features of Apple's latest iPad, which was launched in March, offering four times the number of pixels of its predecessor, the iPad 2.

"I really love the retina display on my new iPad, and I can't wait to see what a retina display looks like on a bigger laptop screen," added Grannis. "Apple already sells the best laptops, and the new ones are going to be to die for - Apple still has plenty of room to expand its market share in the traditional PC and laptop market."

Michael Yoshikami, CEO and founder of Destination Wealth Management, agreed that the launch of new MacBooks at WWDC will resonate with consumers.

"As retina displays begin to move away from iPads exclusively and towards MacBook devices, virtually all MacBook owners will consider upgrading their devices to experience what will likely be shocking resolution for a computer screen," he noted, in an email to TheStreet.

TheStreet will be live-blogging the WWDC keynote, starting at 12:3- p.m. EDT.

The removal of CD-ROMs from the MacBook Pro line would also be an important development for Apple, according to Yoshikami.

It's not just hardware, though, that will be in the spotlight at Apple's annual developer event.

The iPhone maker has already promised to highlight software at WWDC, and looks set to unveil a new version of its iOS operating system, which could include a new map app, tighter integration with Facebook ( FB) and Siri support for iPad.

"I expect the focus to be on a new operating system that will more fully integrate Siri, as well as a navigation system to compete not only with Google ( GOOG) but TomTom," noted Yoshikami, in his email to TheStreet.

Not all Apple investors, though, are even focused on WWDC.

"Honestly, WWDC is not really on my radar," explained Chad Brand, president of Peridot Capital Management and author of the Peridot Capitalist blog. "Now that Apple has gotten so big, major product launches are really the only things that are going to move the needle, so to speak -- I doubt anything coming out of WWDC will really move the stock materially one way or the other."

Brand, who is long Apple, is more interested in two of the tech giant's products that could appear later this year. "iPhone 5 and iTV are the two product launches that matter to me at this point," he wrote, in an email to TheStreet. "I think iTV could really be a strong catalyst, so that's what I am banking on."

There has been chatter that the next-generation iPhone, iPhone 5, could make its debut in October, with the new Apple TV, described as iTV, appearing in time for the holiday season or in 2013.

Apple shares, which have climbed more than 43% this year, were up 1.14% in premarket trading on Monday.
