You really don't know, I'm sure. But we do. Kuo's predictions from
January 2013:
"
- iPhone: Kuo expects that Apple will introduce both an iPhone 5S and a revamped iPhone 5 around June or July of this year, with the iPhone 5S appearing very similar to the current iPhone 5 but carrying a number of upgrades including an A7 system-on-a-chip for better performance, a fingerprint sensor, and camera improvements such as an f2.0 aperture and a smart LED flash. He also believes that the lower-cost iPhone will in many ways simply be an iPhone 5 repackaged into a slightly thicker (8.2 mm vs. the current 7.6 mm) plastic enclosure available in six colors"
- iPad and iPad mini: Kuo forecasts that Apple will update both lines during the third quarter of the year, with the iPad mini gaining a Retina display as the most notable change. He also predicts that the full-size iPad will become considerably slimmer and lighter and adopt the thinner side bezels seen on the iPad mini."
If he's accurate in the current predictions as he was with the January 2013 predictions, you can preorder your iPad Pro. Or rather, we can - you wouldn't know.
