We've arrived at Berlin's IFA 2012 consumer electronics show, where events will kick off on Wednesday, August 29th. Samsung is expected to unveil its new Galaxy Note, an Android-powered Galaxy Camera, and a transforming Windows 8 tablet. Sony made the trip as well to launch a rumored 84-inch 4K TV. We're also expecting to get prices and shipping dates for the 55-inch OLED TVs made by Samsung and LG. So hold tight, all we know for sure is that there are bound to be surprises.
