In what has become a regular tradition ever year the guessing game of when Apple is likely to hold its Worldwide Developers Conference has begun. As noted by Settib.it Moscone's website is now showing the recognisable "Corporate Meeting" placeholder text.
In past years when Moscone's online diary has displayed the two words it has pinpointed when Apple is likely hold its developer's conference. Cementing the rumour further is the venue which is listed as Moscone West in San Francisco where Apple has held the conference for countless years.
Apple often announces the dates of its WWDC in March but broke tradition last year and announced the dates in late April.
