Same old regurgitated news story that basically confirms no-one-knows-nuffink'.
That said, I'm firmly in the camp that is skeptical that we'll see retina iPads so soon. Yeah yeah, the tech exists, but in the volume Apple need by March/April?Really? That's not even bringing price into the discussion, think they'd struggle to maintain the current pricing scheme for such a display at this stage.
I actually wouldn't mind a 2S to come along, very happy with my iPad2 - its plenty fast enough right now, I NEVER use the awful cameras - and would happily skip a 2S, the only thing that'd motivate me to upgrade would be a retina display.
