Support for Kerberos and NegotiateV2 HTTP authentication schemes
CoreText framework for advanced typography support
A simplified API for formatted text

Richer CoreAnimation properties (layers can have shadows and effects; effects can be rasterized for speed)
Text layers for optimized drawing of formatted text
Simplified Beizer path drawing API (formerly a private API)
User-accessible filesystem and built in view controllers for accessing them (note: applications that access files directly and not through controller probably won't be approved)
Simplified gesture recognizer API (available in 3.0 as a private API; some of us have been using this already
Simple CoreGraphics PDF-creation API
Ability for applications to add custom items to the select/cut/copy/paste menu (similar to what my ActionMenu does)
Spell-checker in text fields and web views with support for multiple languages, grammar checking (English-only), address book integration, user added words and SDK access (via AppleSpell; similar to what my Inspell product does)
Custom keyboard views; hardware keyboard (possibly via USB: USBKeyboardLayouts.plist or Bluetooth?)
Support for querying attached screens (AppStore-permitted external display support?)
Simplified zoom support for standard scroll views
SpringBoard maintains orientation

Ability to set the desktop background (private)
The beginnings of file upload support in Safari

Legacy code from iPhone 1.x is still around

(if stripped out, could save some RAM for memory-constrained devices)
Swipe and flick gestures on keyboard
Split-view and popover styles
Handwriting keyboard is being prototyped
"Book" view controller
"Peripheral views" are being prototyped (not 100% sure what this is, but appears to be plugins that hardware vendors can inject into all applications?)

Support for DMG and other disk image formats (in the public frameworks path?)
Printer support is being prototyped
Speech Synthesis is mentioned in public headers (is currently a private API)
Slideshow integration with iLife
