That seems impossible to me but of course I don't have inside information.
I suspect that Apple is not interested in adding complexity and weight to the iPad to accommodate the higher resolution. This can happen eventually but it doesn't seem to be the case at this time, not using existing technology. On the other hand there could be technology available now to make more resolution on the iPad viable.
I guess we'll find out late next month or in March though I do think that bringing out a heavier, pricier iPad is not on Apple's radar.
I disagree there are a lot of android tablets with better resolution than the iPad and a lot more moming this year. If apple does not fo retina there harwear will look out dated and over price. The same for LTE, if CES show somthing is that all new tablets/phones will be LTE...
