Apple is restricting retail employees time off in September, according to German site iFun.de.

This could be a hint of an iOS 8 announcement in WWDC 2014 and an iPhone announcement and launch in September. Included in this launch pattern are new iPads coming out in October.

A September launch for a smartphone is what Apple has been doing in the past, launching its new flagship models in last month of the third quarter, which some call "iPhone month", and it seems it will do the same this year.

iPhone 5 was launched in September 2012 and iPhone 5s in September 2013. There is much anticipation for the next flagship smartphone, the iPhone 6. Many are hoping that Apple will join larger screen trend. Many speculate it will come in two screen size variants –  4.7 inch and 5.5 inch models. The upcoming iPhone is set to be thinner than its predecessors, faster with the A8 processor chip and launch in the fall of 2014.

Aside from iOS 8, iPhone 6, and a rumored 12-inch MacBook Air Retina, Apple is also expected to release a new Apple TV, new OS X for Mac and the "iWatch" wristwatch.

If all these launches push through, the iPhone maker indeed needs to have enough staff for a busy second half of 2014.
