Cases with a little play to them like the $20 CaseCrown Standby should be able to accommodate the next iPad so long as Apple doesn't pull a big design surprise.
In preparation for Wednesday's launch of Apple's next-generation iPad, CNET's been contacted by a few accessory manufacturers gearing up to release "new" products that will work with the iPad 3--or whatever it's called.
Those quotation marks around "new" are there because it appears that while all the new accessories announced out of the gate will be billed as iPad 3 accessories, they'll also work just fine with the iPad 2.
Three different company reps said they expected the next iPad to be similarly sized and that there would be only minor changes to the thickness of the device. While no one was 100 percent certain of that (one rep said, "We've been told there will be some minor changes in the thickness, but we don't have any specifics.") these companies have enough confidence in their belief--and perhaps their sources--to stick with the iPad 2 as a stand-in for the next iPad.
