The good news is that under the hood things remain just as expected – a dual-core A5 processor will be the beating heart of Apple's new tablet, backed up by 512MB of RAM and an upgraded GPU. At least one camera will be added to the iPad 2, probably on the front for FaceTime conversations, but a second one on the back with HD video capture capabilities will not be a surprise either, although you may look silly waving your tablet around to take shots.
It is speculated that a preview of iOS 5.0 will be displayed at the event along with its SDK for developers. We are also expecting words about Apple's cloud services as they still tend to be a bit unclear. Hang in there for another five days, until we finally get enlightened.
