Just thought I'd start a thread since we're likely to be fast entering silly season, and I thought I'd come up with my own speculation for silliness's sake:
iPhone 5 Pro
3.7" 960x640 LCD (Edge-to-Edge horizontally to keep the same dimensions?)
A5 (similar clocks but thermally limited when using both cores or GPU)
Qualcomm MDM6660 14.4Mbps & 5 HSPA Bands + EV-DO CDMA
NFC via Broadcom? Or no NFC? (cannot be NXP/Inside Secure)
Audience eS310 voice processor (replacing Audience A1026)
1GB 64-bit LPDDR2 DRAM
Sony 8MP rear camera
720p front camera
32-64GB NAND
iPhone 5 Nano (assuming Apple doesn't keep selling the iPhone 4 which seems rather likely)
3.5" 960x640 LCD Edge-to-Edge (smaller home button) OR 3.2" 480x320 LCD (more realistic cost-wise really) - either way lower quality than iPhone 4 (ala iPod Touch 4G: worse contrast etc.)
A4 (remember it's actually smaller than the 3GS SoC)
ex-Infineon XMM 6160 7.2Mbps (same as iPhone 4)
ex-Infineon UE2 RF & 5 HSPA bands (replaces UE)
512MB or 256MB LPDDR1 (A4 can't use LPDDR2)
720p <2MP rear camera (see: iPod Touch)
VGA Front Camera
Cheaper materials
Smaller battery
Unsubsidised Pricing: $249-329 for 8-32GB
Subsidised Pricing: $0 for 32GB (slightly cheaper contract than iPhone 4)
I know it's not generally accepted that Apple would release an iPhone Nano-like product this year (and the name iPhone 5 Pro is rather unlikely but that's besides the point), however notice the components are exactly what you'd expect from a cost-optimised iPod Touch 5G except for the presence of a 3G baseband (the camera might be controversial but it saves on cost and would help make it very thin). If Apple wanted to be especially secretive, they can simply pretend they're negociating for iPod Touch components, not iPhone ones. And a next-gen iPod Touch is suspiciously absent from the iOS 5.0 device list... And I didn't say this was likely, just doing my part making silly season, well, silly
EDITs: Various small changes (typos, clarity, extra points)
