I know at least 2 people who'd love to have the option to buy Wacom pens for iPads. Right now it doesn't really work unless you use some very hacky solutions. I wish Apple supported pressure sensitive pens.
I'n also still hoping for an 11"-12" 16:9 iPad Pro (they can just make it longer like they did with the iPhone 5 that comes with a keyboard. It should basically be an iPad laptop (not hybrids, no point) that costs $700, and comes with a new A8 processor in spring, or at least A7X, and maybe 64 GB by default.
