The next edition of the iPad could have a lot in common with Samsung's Galaxy Tab. GigaOM reports that analyst Ashok Kumar has stated that Apple might be working on a new 7" version of the iPad for launch in 2011. This slate will pack both front and rear-facing cameras.
Let's put on our thinking caps for a moment here. We know that a new iPad is coming out next year. Apple hasn't announced it, but we have the iPhone's upgrade schedule to use as a guide. The industry is moving too fast for Cupertino to sit on their laurels for a full year. The front-and-rear facing cameras are definitely likely, possibly even "all but" guaranteed.
So now we're down to that 7" form-factor. Apple might want to go with a smaller screen in order to reduce the iPad's weight and make holding it one-handed for extended periods of time easier. Or they might be trying to cut on costs more. Personally, I doubt any 7" iPads will be released solo. Apple may increase the line to include 7" and 10" models, though.
