As May marches on, the summer rumor mill is starting to crank up in Apple land.  Word came out today that Apple is planning on having an all-hands employee meeting in US retail stores on Sunday, May 22, but what could be in store? 

According to macstories, a tip was received from a trusted source regarding the meeting, and that it would start at 7 AM, considered an "unusual time," as Apple tends to hold a meeting of this sort on Sunday evenings, once stores close.

It's unknown however, as to what this meeting is entailing.  Potential speculation could be around: WWDC kicking off in San Francisco on June 6, Apple could be training employees for the oft-mentioned new MobileMe or iCloud, or perhaps another product.  Of course though, Apple is also celebrating the 10th anniversary of their Retail function this week, and several websites have claimed that Apple was planning on setting up special events and store merchandise for the anniversary.

BGR was also able to provide some more details on the meeting:

During the overnight shift, it's going to be required that employees lock cell phones in the main office.  They will also have to sign an NDA with Apple.

There are a wide variety of roles, we're told, for the overnight shift.  This includes all visuals staff, a manager, a business team member, a few Genius team members, one back-of-house employee, and a few generic Apple specialists.

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.

Apple employees will be putting up black curtains at all stores so that people walking outside cannot see inside.

Employees have had to download gigabytes of data from Apple corporate labeled, "training" in a password-protected zipped folder that won't be accessible to managers or anyone else until Saturday afternoon.

What do you make of this potential meeting readers?  New products?  Tenth anniversary celebrations?  iCloud?  Feel free to speculate below!
