Method 1

There’s a couple of videos on Mircosoft Channel 9:

ASP.NET 4.0 Roadmap by Scott Hunter
It seems like someone has made session notes on this talk, as well.
New Features of ASP.NET 4.0 by Steven Walther

Quoted (partially) from those session notes on the linked blog post:

Web Forms

Developers can manage control IDs that affect rendered client ID
Remove ID bloat, and ‘mangling’
CSS:

Ideally remove the need to use CSS adapters
Defer to CSS styles and bypass existing style properties

non-inline style attributes

Support non-table-based HTML rendering

URL-routing for web forms

Friendly url handling for web forms
configuration model for url routing

View state

Disable on the page, enable on specific controls – they will provide granular control
of viewstate – today it is backwards
Disable on control, enable on child controls
GridView/ListView work better without viewstate

ASP.NET dynamic-data

Ajax

Continue ASP.NET Ajax innovation : RIA
Appeal to JavaScript Developers
Provide support for the page developer
jQuery including Intellisense
Templates and data binding

Client side handling, REST or Web Services
Covers page developer and component developer scenarios

DOM manipulation, selectors …
Ajax higher-level components

Ajax Control Toolkit is a part of the strategy – they will make the toolkit part
of the overall ASP.NET package
New controls

Centralized script libraries and break-up for performance

ASP.NET MVC

Appeal to those wanting separation of concerns, TDD, full control
Ruby on Rails, Django, PHP
Building on from ASP.NET MVC 1.0
ASP.NET MVC (Model View Controller)
Asynchronous controllers
Sub-controllers & Views
Declarative controls

ASP.NET Core

Address customer pain points
Improve scale and performance
Cache extensibility and performance:

Enable caching like Velocity

Method 2

There are quite a few:

static client-side ID’s
better dynamic data support
better support for the routing feature (made popular by ASP.NET MVC) for webforms apps
many Ajax enhancements
