The iPad 2 will not have a "retina display." That's the realization that most people have been coming to for some time now. Not long after the iPhone 4 came out, I read an article which mentioned the very significant challenges in bringing such a high resolution screen to a display the size of the The iPad.
John Paczkowski over at AllThingsD cites a report originally from AppleInsider suggesting the iPad 2 "will feature the same 1024×768 resolution display as its predecessor."
Which really shouldn't come as a surprise to anyone, but I foresee many a blogger and pundit "dinging" the iPad 2 for not having a retina display
