( CNN ) -- All the tech world 's eyes will be on Apple Monday , when the computing giant 's 24th annual Worldwide Developers Conference kicks off in San Francisco . As its name suggests , the weeklong gathering lets Apple host presentations and workshops for the people who make a living writing the apps and other software that run on its products . But its opening keynote almost always makes news . The conference has been the launching pad for two phones ( the iPhone 3GS in 2009 and the iPhone 4 in 2010 ) and several new , or updated , Macs . This year , the former seems highly unlikely . The latter ? Maybe not so much . Fans are clamoring for some excitement , because Apple has n't introduced a major new product since the iPad Mini last October . And with growing competition from such rivals as Amazon and Samsung , there 's always the chance that the secretive folks from Cupertino are cooking up something big . So here 's a look at what to expect from WWDC 2013 . Apple 's keynote begins Monday at 1 p.m . ET . A new iOS . The safest bet for WWDC is that Apple will introduce iOS 7 to the world . For the first time , Apple vice president Jonny Ive is responsible for the update , and reports have suggested the mobile operating system will be `` black , white and flat all over . '' Unnamed Apple sources have popped up on the Web , saying that much of the color , gloss and shine will be removed from the look of iPhone , iPad and iPod Touch screens in favor of a simpler black-and-white theme . Style aside , there will almost certainly be a host of new features to announce as well . Reports have centered on improved in-car support for Maps and Siri , along with new integration for third-party ( and non-Google-owned ) apps like video site Vimeo and photo site Flickr . The update also could bring Airdrop , which allows easy Wi-Fi sharing between Apple devices , to mobile . New MacBooks . The MacBook and MacBook Air laptops are both due to be updated , according to Apple 's once-a-year pattern . And the timing is right : Intel just announced a more powerful processing chip . It will be a challenge for Apple to shrink the already ultra-slim MacBook Air much further . But if the rumors are true , the beefier MacBook Pro may give way to a new , sleeker version of itself . Apple also could introduce a refreshed Mac Pro desktop tower for those deep-pocketed office managers who prefer to order the freshest machines . A streaming-music service ? It seems like only a matter of time before Apple leaps into the increasingly crowded streaming-music market led by Pandora , Spotify and others . Apple 's been making deals with record labels such as Universal Music and Warner Music Group , which would allow them to stream songs to users as part of a free or paid-subscription service . Observers expect such a platform , possibly called iRadio , would exist apart from iTunes , Apple 's digital-media service , and focus on mobile devices . Longshots . Sure , there are realistic expectations . Then there are the really fun ones . Hope springs eternal in the fanboy 's breast , so we wo n't be the ones to shoot down hopes for a big , `` one more thing '' surprise . And , hey -- CEO Tim Cook has already teased `` exciting new product categories '' this year . According to observers , an Apple TV set has been on the verge of being released for years now . ( Experts are just sure the company is going to roll out a TV set . Eventually . ) A little over a year ago , there was a bizarrely specific Best Buy survey asking loyal customers about the `` concept '' of an Apple TV . It seems like too much of a real thing to never happen . But will it happen next week ? Not likely . Joining the mythical `` iTV '' is an Apple watch -- another product everybody is sure is coming , despite Apple having said no such thing . Wearable tech is becoming a huge field and Apple would surely like to cool off some of the heat generated lately by Google Glass . A watch feels slightly more likely than a TV , but not by much . This fall , just in time for holiday shopping , seems a more likely release date for one or both . And , quite possibly , for a new iPhone . There have been some rumblings about a possible new iPad . It has been a little more than seven months since the iPad Mini was unveiled , though , and only four months since Apple offered a 128GB version of its bigger counterpart . So a new model would be a surprise . What do you want to see from Apple ? Let us know in the comments .
Apple 's annual Worldwide Developers Conference kicks off Monday . Observers expect a new mobile operating system and refreshed MacBooks . A rumored smart watch and a possible Apple TV set remain longshots for now . Comment:
