In a note to clients Kaufman Bros. analyst Shaw Wu is expecting some big announcements beyond iPhone OS 4 and a likely new iPhone at June’s Apple Worldwide Developer Conference. Among them is a new Mac Pro.

“AppleInsider” ( concurs, expecting a pro Mac desktop that adds a total of 12-cores from Intel’s latest Westmere architecture to the high-end desktop. (Apple is also expected to release a second LED-backlit Cinema Display, measuring 27-inches diagonally and resembling its existing 24-inch model,” says “AppleInsider”). And Wu also thinks we’ll see a revved MacBook Air and a web-based version of iTunes.

“Sources tell me that in the past few weeks, Apple has started signaling to the labels that it’s interested in a web-based version of iTunes, its dominant music retail platform,” Wu has told clients. “But those conversations are preliminary at best. So if you’re expecting to hear about an ‘’ offering in the near future–like during Apple’s June 7 developer conference–you’re likely to be disappointed.”

On the other hand, Piper Jaffray analyst Gene Munster is expecting no big announcements beyond those concerning iPhones at WWDC 2010. However, he does say a peak at Mac OS X 10.7 might be “possible,” but not likely.

Apple will kick off its annual Worldwide Developers Conference (WWDC) with a keynote address by CEO Steve Jobs on Monday, June 7, at 10 a.m. This year’s WWDC sold out in a record eight days to over 5,000 developers.

The five-day event running from June 7 to June 11, is focused on providing advanced content for skilled developers across five key technology tracks: Application Frameworks; Internet & Web; Graphics & Media; Developer Tools; and Core OS. Apple engineers will deliver over 100 solutions-oriented technical sessions and labs.

There will be five iPad and five iPhone Apple Design Award winners announced at WWDC 2010 (alas, Mac apps need not apply). There’s no requirement to enter and winners will be selected from the Apple App Store based on criteria that includes design, technical excellence, innovation, quality, technology adoption and performance.
