Yep , i received the the new with ZBrush 4 download from
Pixologic

The new tool ShadowBox for example is really amazing to create anything easily as hell. It makes me think a lot at 3D Coat Voxel tools like Hide or create primitive, but now it's ZBrush !
Hard surface now is totally possible :
ZBrush 4 Hard Surface modeling And i don't know lot of companies doing a free upgrade on new version of software.
To people owning that amazing software just enjoy.
