I've iPhone5, iPad3 and rMBP15. I am spoilt by retina displays. I cringe wherever I've to use my wife's MBA13 and iPad2. Given Apple's iterative improvement, I'm not too surprised iPad Mini doesn't have retina in the 1st pass. Which got me to do some 5-min calculations: With an LCD size of 160mmx120mm, a 2048x1536 screen would yield 326 PPI which is the density of iPhone! Coincidence? Bottom line, it'll be easy to put retina on iPad Mini, just ask the supplier for a bigger (7.9" instead of 4") piece. Since this is so easy, I think 2013 Fall, iPad Mini (Gen 2) will see its retina display. When this happens, what happens to the iPad? Given the screen transition exercise in iPhone5, my guess is physical x & y dimension will remain, aspect ratio will remain, but more pixels will be added. 2560x1920 in iPad's LCD 198mmx148mm would yield 329 PPI, not too higher up from 326. On the other hand, since 2048x1536 is already retina, why would Apple upgrade it to 2560x1920? It's not significant like pixel doubling. Can iPad Mini and iPad exist side by side with the same pixel dimension, 2048x1536? The related question, for all the Apple products with retina display, what's the upgrade path for the screen? Retina 2X?
