I was wondering are we going to get zen garden demo at Apple wwdc 2014 as downloadable content from marketplace like we got vehicles game, sci-fi hallway and etc.
This was in the announcement in our original post:
We are very excited about the new
levels of graphical quality and
efficiency made possible by Metal, and
will be making Zen Garden available in
the App Store after iOS 8’s public
release, as well as making the Metal
code in Unreal Engine 4 available at
an appropriate time after the beta
access NDAs are lifted.
As for Rivalry, I’m not sure that this will be released other than the video. The reflections subway example is currently available on the Marketplace.
