Apple has given more stuff to rumor mills to chew on. If tech enthusiasts are tired of reading up the latest rumored iPhone 5 feature, they can now ruminate over the possible ways in which the tech giant is going to celebrate the 10th anniversary of its retails store opening.

Tech websites have gone gaga over a possible product launch on May 19. And as usual, the secretive Apple has left everything to be guessed. Except that some sources have told tech website BGR that some unusual preparations are going over at Apple stores in the run-up to the May 19 anniversary.

Apple stores have apparently already received hardware to install, and are expecting more hardware to come on Friday or Saturday. All materials that Apple stores have received have been instructed to be under lock and key until after close on Saturday night, the report says.

AppleInsider has speculated that if the anniversary is going to be about a product launch, it could be the iCloud, Apple's cloud-based music streaming service. But then it's a wild guess.

However, there has been robust talk about Apple launching a revamped MobileMe service soon. MobileMe, which offered cloud service for email, contacts, calendars, and online storage, was withdrawn from Apple stores in February, fuelling speculation about its launch in a new revamped form.

Augmenting this prospect, Touch Review reported last week that Amazon has ceased sales of Apple’s MobileMe service.

According to the report, the purported iCloud will offer a cloud-based ‘music locker’ that allows users to store their music collection online and stream it from internet-connected devices like iPhone, iPad, and iPod touch.
