What dpi, according to Apple's published math, would it take for this rumored device to be considered Retina.
If that number is close to something we've seen produced then the possibility becomes better.
I've been looking at available resolutions vs. a brand new one.
1024x768, iPad1/2 resolution, 4:3 A/R, 164PPI
Would look very good, low-to-no app issues (from development to current compatibility). Wouldn't require anything over an A5 (like is present in the iPad2 and iPod Touch), the lower power version would be perfect.
2048x1536, iPad 3rd Gen res, 4:3, 326PPI
Would look stunning, again, low/non issue for apps/development (assuming proper style guide design, etc.). Would require an A5X (high power reqs, hot), or a new A5X 3Xnm variant ... or, the new A6. I'm not sure if the A6 in it's current flavor could drive this resolution to acceptable performance levels[?]
We're talking about ~4.3 times as many pixels in the 3rd Gen vs. the iPhone 5.
OK, so suppose Apple says, **** it, new resolution, deal with it. They'll likely keep it 4:3, but maybe come in somewhere that results in the display being 240-255PPI, like 1600x1200 (~254PPI). FWIW, that resolution is still ~2.6 times more pixels vs the iPhone 5, but maybe an A6 with a little clock boost could handle it.

Other way around actually. The higher storage devices are becoming less needed. With iCloud, and all of that including iTunes Match, I see no reason why people want 64GB at all. I personally only want 8-16GB.
Having owned 16GB and 32GB iOS devices I can tell you, even with iCloud, and iTunes match, 16GB gets a little cramped
