I read on the krita.org website[1], that krita sketch was seen running on nexus 7 at the MWC, and that is very exciting Is the package available somewhere? (zypper does not find it with the repositories I have)

As far as I know there are no packages yet. Krita Sketch is currently on the way to be merge into master, so I guess it will be picked up by packagers after that.
