Windows 8 50/50 split fullscreen apps?! Video!

Wuuuuuuuut?

I just came across this video of the Project Austin (a note taking app for windows 8), and it apparently shows the mailing app and the Project Austin app running side by side in an (almost?) 50/50 split, instead of the typical 1/3 or 2/3.


The fun begins at 2:08..

Do you guys think this means that Microsoft will allow apps to be split equally in fullscreen mode?
