I see Apple putting the iPad in its yearly rotation such as the iPod line and the iPhone. Not the same time as those, but roughly a year from when it first released which I suspect would be around April 2011.
I'm hoping soon, just got a check from a family member as a gift with the instructions to use it to buy an iPad - awesome - but I'd hate to buy it and then the next gen comes out soon with the anticipated front facing camera, etc.
I know it's extremely unlikely, but I'm crossing my fingers hoping for an announcement at the 9/1 press conference (I know, I know, no way, but hope springs eternal...)
It would be nice if Apple bumped up the RAM for the Xmas holidays. Would get a few fence-sitters, like myself, to pull the trigger. I guess it all depends on what kind of inventory they're managing.
