Apple's WWDC 2014 developer conference is set for June 2 and we're already feverish with anticipation.

What will Apple announce? iOS 8? An OS X Mavericks successor? An iPhone, an iPad, some Macbooks? For the sake of our wallets, we hope not all of the above.

As in previous years, the company has designed a natty new logo for the occasion. But what can we tell from these colourful squares and their optical shenanigans? We've taken a look back at previous years invites with the benefit of glorious hindsight to see what's what.

2008

WWDC 2008

The original iPhone was announced at MacWorld in January 2007 and speculation about an iPhone 3G was rife ahead of WWDC 2008. The invite, showing a landmark (the Golden Gate Bridge, obviously) split into two hinted at two major announcements - and so there were: Hello iPhone 3G, hello App Store full of third-party apps. Also unveiled were iOS 2.0 (!), push notifications and MobileMe (RIP).

2009

An uninspiring look for WWDC 2009, with the iPhone and its apps taking a rather drab centre stage. All we could really tell about the show from the teaser logos was that the iPhone was going to be the focus.

We were hoping for iOS 4.0, a new iPhone and a major Snow Leopard update to "give Windows 7 a run for its money" before Steve Jobs took to the WWDC stage to reveal the iPhone 3GS, an underwhelming Snow Leopard update and a new MacBook Pro line-up.

Our phone expert Gareth Beavis was also unimpressed by the iPhone 3GS, saying that it "failed to lay the smackdown on the Palm Pre." Oh Gareth.

2010

WWDC 2010

Apps were firmly on the menu for WWDC 2010, but the logo didn't exactly hint at the iPhone 4 that Steve Jobs ended up announcing at the conference. Described as the world's thinnest smartphone, it launched with a now-laughable 9.3mm depth, a mobile gaming game-changing gyroscope and a host of antenna-related problems.

2011

Now here's an image that hints at the conjoining of Mac OS and iOS - all those apps sitting in the MacBook-esque sea of grey? It was the logical conclusion. Unfortunately, it was also the incorrect conclusion.

The iPad had launched in the previous year and we expected iOS 5 to be announced at WWC 2011 hand-in-hand with the iPhone 5. What we got was iOS 5, iMessage, Newsstand, over-the-air updates, OS X Lion and the phrase "Post PC". In a shock move for Apple, the iPhone 4S wasn't unveiled until October 2011.

2012

WWDC 2012

Here's where things started getting colourful. The app-ish squares that make up the Apple logo hinted at news of iOS 6 in that they looked like app logos and we were expecting iOS 6. The show sold out in record time (under two hours) and did indeed see the launch of the new OS. The logo didn't exactly tip us off to the debut of the ill-fated Apple Maps app, though.

2013

WWDC 2013

Well hello, new slimline font for iOS 7. We could only identify that with the benefit of hindsight, but Apple hadn't been this obvious since the "landmark" invite of 2008. Rumours that a whole new look for iOS was on the cards percolated for weeks ahead of WWDC 2013 and we weren't disappointed by the flatter, cleaner iOS 7. Mac OS X also got a rejig in the form of Mavericks, and Apple also launched iTunes Radio.

2014

WWDC 2014

So what can we divine about WWDC 2014 from all this? Well, not a whole lot more than the obvious. We're expecting iOS 8 but with the iPhone 5C-ish colours and iOS 7 font present on the new logo, we don't think it'll be a huge change from the previous iteration (at least as far as design is concerned).

There's nothing to suggest a new iPhone. There's nothing to suggest a new iPad. There's nothing to suggest an Apple TV set or an iWatch. But it's Apple, so you really just never know.

We'll be reporting on the big WWDC 2014 keynote live on June 2, so stay tuned for all the official news as it breaks.
