The iPhone 5 will be a dual-core phone running the A5 chip. LTE 4G, compatible with both AT&T and Verizon. Will not move to T-Mobile (due to possible buyout), but MAYBE (big maybe) a move to Sprint. Larger screen (just less bevel, same ppi), same overall size (not a huge clunker like the Droid X2 or something). I'm believing these beveled mockups with a larger gesture-enabled home button. So that means thinner, but somehow pull off same battery or even increased battery life (A5 chip has better power management). Camera will be bumped to 8MP and front will have a slight bump too. 32GB and 64GB models. May see price raise to $250 and $350 on contract (like other 4G phones).
The iPhone 4S will be announced as a replacement to the iPhone 4. Same general design. Cheaper components (plastic back compared to current glass, cheaper and easier to color), will run a single core A5 chip (likely cheaper to produce A5's in bulk than keeping the A4 in production, it may even be a dual core A5 with a core turned off). This may be a "Cloud" phone with 8GB or less internal memory. Expect no contract option (most of the world runs this way), priced at $300-$400. $100 or $150 on contract.
The iPhone 3GS may still live on in it's current fashion. It'll hit free on contract. $200 off contract. (I expect this to die off this time though).
RELEASE DATES:
Most people think the iPhone 5 was pushed back so that Verizon had it's fair time with the iPhone 4 (5-6 months). Verizon should know (as well as Apple) that people are waiting to purchase an iPhone now. The iPhone 5 was pushed back due to 4G LTE testing, but Apple is hiding it under the iCloud + iOS 5 testing veil. (Wishful thinking, it's likely really due to iCloud and iOS 5, haha).
So yea, September 7th announcement and pre-order with September release for U.S. and select countries. China Mobile coming live in October.
IPAD 3/2 PRO
I'm still up in the air on this one. I could see an iPad HD with retina display and Final Cut Pro on the iPad (they don't really care about tarnishing that name anymore). I think they'd just wait for the iPad 3 instead of making a consumer line and pro line. They seem to be stepping away from that trend in their laptops.
