I am super excited for this.

Here is a tl;dr of the features page:

New user interface
iPad optimization
Built-in web browser
Cheating support
Supports games for old GameBoys
Skin customization which can be downloaded here.

Looks sexeh.
Will it require a jailbreak, or will it just need to be installed normally?
They say they aren't putting it in the marketplace.
