Last week saw a spike in "iPad 2" sightings, led by an Engadget post about a black iPad 2 case spotted at the Consumer Electronics Expo.

The case included cutouts for a camera in the front and back, plus and a hole for speakers.

Then on Wednesday, an anonymous CES attendee sent a video (see below) to Slashdot that zooms in on an alleged iPad 2 prototype seen at CES.

The video appears to confirm features of the device implied by the case spotted by Engadget and other blogs: two cameras, a speaker, thinner chassis.

So is the device legit? Is it possible that some of Apple's parnters have data on the next iPad, and some of that data is now leaking out?

While it seems reasonable that Apple would give upcoming product specs to accessory makers so they can start designing sleeves and slips and whatnot, manufacturers contacted by PCMag said this was simply not the case.

"Griffin does not receive any demo/dummy products before the product is announced, nor are we given any prior information or specs on Apple products. You can often find Griffin employees waiting in line alongside anxious consumers to purchase new Apple products," said Jackie Ballinger, marketing director at Griffin Technologies.

Belkin spokeswoman Anabelle Apley agreed, "We do not receive any demo or dummy products from Apple before an announcement [is] made."

Other companies declined to comment directly about Apple.

That's not to say the "iPad 2" cases are offbase; after all, last year iPod Touch cases with camera holes appeared on Chinese websites before the product was launched, and they turned out to be accurate. Is that what's happening here? Draw your own conclusions from the video below.
