we're introducing a new way to bring people directly to your app from a Tweet, and we're adding new types of Cards, so you can more creatively show your content on Twitter.
First, we're introducing mobile app deep-linking in Cards –– a new feature that closes the loop between content creation, content discovery and app downloads. With mobile app deep-linking, users will be able to tap a link to either view content directly in your app, or download your app, depending on whether or not they have your app installed.

Second, we're adding new types of Twitter Cards:
App: Show information about your app, including app name, icon, description and other details like rating or price. Just give us your ID and we will display information about your app from the App Store or Google Play.
Product: Represent products by showing an image and description, along with up to two customizable fields that let you display more details like price or ratings.
Gallery: Represent an album or collection of photographs via a preview of the photo gallery. This card indicates to a user that a gallery has been shared, rather than just one individual photo.
Just saw this, it's brilliant as a lot of users are using Twitter from a mobile device - me included - and having the ability to download apps directly is great. Looking a the twitter cards, I see them coming in handy as well.
