SAN FRANCISCO, MACWORLD/iWORLD 2013 – The doors of Macworld/iWorld  open up tomorrow morning, but we’ve already taken a quick tour of the Moscone center to get an early look at the action.

Exhibitors are rushing around trying to put the finishing touches on their booth, but it looks like some of them will be burning the midnight oil as a lot of booths still need a ton of work. We’ll be back tomorrow morning to cover all the cool new products and TechTalks, but for now, here’s what it looks like behind the scenes of Macworld/iWorld 2013.

Many people thought that without Apple’s injecting blood directly into the arteries of Macworld, the expo would quickly shrivel and die.

They were wrong. Apple may not have participated in the event since 2009 but things are still going strong. Macworld has transformed itself from an Apple launch event where Cupertino  announced products like the original iPhone and taught customers how to use them, to an event where people celebrate the culture that permeates Apple fans and binds them together.

In three short days, thousands of iFans across the globe will converge on San Francisco’s Moscone Center to celebrate everything that is great about Apple. It’s going to be a great show. Already, Macworld/iWorld 2013 is set to be one of the most entertaining Macworld conferences in recent memories. It’s going to be packed with celebrities like Ashton Kutcher and Will.i.am, while over 350 companies show off their new products to Apple fans who will love getting to hangout with each other and swap stories on everything Apple.

Here’s what to look forward to this week at MacWorld/iWorld 2013:

Prepare yourself for a another look at OS X Mountain Lion and a peak at iOS 6, because Apple’s annual Worldwide Developers Conference looks set to begin in early June. San Francisco’s Moscone Center — the company’s favorite venue for WWDC — has been booked up for a mysterious “corporate meeting” for one week starting June 11.

Apple broke from its traditional June unveiling for the iPhone 4S, choosing instead to launch the device at a dedicated “Let’s talk iPhone” event in October. But we may not have to wait until October of this year to see the iPhone 5.

According to one analyst, the sixth-generation device will get back its traditional June announcement at Apple’s Worldwide Developer’s Conference in 2012.

This year’s edition of Macworld, taking place January 26-28, is shaping up to be a bit of a departure from Macworlds of the past. 2012 is a year of evolution for the event, now branded as Macworld/iWorld.

And that evolution begins tonight with a blast.

We’re already expecting this year’s iPhone event to be a little different to those that we’re familiar with. Not only will it take place in October, rather than June, but Tim Cook will take Steve Jobs’ place on stage, and the event won’t take place at the Buena Center for the Arts in San Francisco. Instead, it will be held on Apple’s campus in Cupertino.

Mark your calendars: the next iPhone will be revealed sometime between June 5th and June 9th, 2011, as Apple has already booked those dates at the Moscone Center in San Francisco for this year’s WWDC.

Although the Moscone Center’s website officially lists the early June event name as a “Corporate Meeting,” this anonymous description is usually deployed by Moscone Center management to refer to Apple events.

Apple’s next iPhone is traditionally announced at each year’s WWDC event held at the Moscone Center sometime in June.
