This revelation comes courtesy of a serial leakster who often gets sent Computer-aided Design (CAD) schematics, allegedly from factory sources, and provides them to graphic designers to flesh out renders of upcoming devices that are a step above, say, someone's concept images based solely on rumors. Even they are not sure, however, what the doohickey that looks like a dock connector of sorts near the charging port will do. The premise so far is that this is the Smart Connector moved there for added functionality when the iPad is docked in portrait mode, but we'll see what Apple has really meant very soon.
Now, off to the design itself. The curved sides of the current crop will be replaced with more edgy ones, it seems, and the bezels have been drastically shrunk all around, placed symmetrically between the screen and the edges. The display has rounded corners like on the notch-y iPhone, but a notch is nowhere to be seen, thankfully, and, overall, the new iPad Pro looks slabb-y and with a kind of industrial elegance over the current edition.
There is a mysterious elliptical button-looking or tray thingy on the right where the volume keys are, whose purpose is yet to be guessed or revealed. Throw in the four corner speakers and herald the return of antenna lines at both ends, and this is probably the most exciting update to the iPad line in a while, what do you think?
