Here’s the horizontal character sheet from Heroes of the Fallen Lands (click for a larger version):
The character sheet can fit on one page, which is great. It will require you to write pretty small, though.
There are 26 lines for Powers and Feats, which includes Race Features and Class/Path/Destiny Features too, I guess, since there is no section set aside for those. The PHB character sheet had something like 70 lines for all that information, and it sometimes got crowded at that.
There’s no place to write down your Paragon Path and Epic Destiny.
There is quite a generous allotment of space for your Character Sketch, however! Hooray!
