I still haven't picked up an iPad yet, though I'm pretty convinced I will soon -- even if I don't need one myself, there's obviously a lot of great apps out there to try. But already there's rumbling that the camera train is due for a stop at iPad station. Apple is hiring a new member of the iPad team, and they're asking for a strong ability to "test still, video and audio capture and playback frameworks." We've already seen that there's room in the device for a camera, so it's a pretty good guess that whenever the next version of the iPad rolls around (hopefully later rather than sooner for you early adopters), there will be a camera included.
And in other iPad news, there are also rumors going around that the iPad's camera connection kit might support USB Audio as well. That's a bit of a surprise -- you wouldn't expect a kit for connecting a camera to also have USB Audio drivers included, but it is basically just a USB connector for the iPad's docking port, so maybe some crafty engineer at Apple has included support for another standard just for the heck of it. I'm sure plenty of audio pros will be grateful if it's true.
