That, and looking at what they list as features. It's..

no unimesh,

no new figure,

the Superfly improvement list is vague

an  HDR dome... I already have from several sources

the content creator improvements are not for me as i am an end user

Included content reorganization... I already have that content

In short, unless there are a bit more meaningful details about what the Superfly improvements exacly are... this is just not telling me why someone who already has P12 should upgrade???
