The Internationale Funkausstellung Berlin (IFA) is scheduled to open on Sept. 5 in Berlin, and it's expected to draw a lot interest as many of the big tech companies are slated to put their new devices on display. The five-day exhibit has raised a lot of speculation on which companies will launch what device, and avid tech enthusiasts have shared what they think will be presented during the exhibit.

The release of the Samsumg Galaxy Note 4 is predicted at the Berlin IFA event. Samsung has had "a tradition" of releasing their Notes at the IFA, and there is no reason why this year would be any different. There is a possibility that the Note 4, if it will indeed be introduced at the conference, will sport a larger screen, perhaps 5.9 inches or above, and most likely upgrades in the processor, RAM, and graphics. Samsung might also release an upgrade to the Samsung Mega.

It is also believed that Sony will take part in the conference with the introduction of Sony Xperia Z3, as well as the Z3 Compact. If there is a next generation to the Z series, then the Z3 will most likely have a Snapdragon Qualcomm 801 processor and 1080p display; and its compact partner will run on a 2.5GHz processor with 2GB of memory.

Wearables will also be a big thing at the conference, and companies like LG, Motorola, and Samsung are likely to put their latest smartwatches on display. LG has already teased the public with video clips of a round LG G Watch, and there's a chance that Sony will have its Sony Smartwatch 3 on display. Asus could also be among those with a new wearable gadget.

Mobile Burn adds that Huawei will likely introduce Ascend Mate 3 and Ascend D7, while Microsoft will perhaps put more budget Lumia phones on display. HTC's exhibit remains to be seen.

Motorola will also have its own press event on Sept. 4 in Chicago where, it is speculated, the company will introduce the Moto X+1, as well as the Moto G. But the most anticipated release is the Moto 360 smartwatch.

Apple, of course, has long been rumored to have an event scheduled for Sept. 9 where, it is said, the company will launch its iPhone 6 and its own wearable iWatch.
