I wasn't planning on buying it - but then, I wasn't really the market for it. I think it was aimed at two crowds - those who were clamoring for an updated PHB with errata included, plus players who joined with Essentials and wanted access to the older material.
I think it would have sold, but not spectacularly well, so I think cancelling it was the right call.
The only thing that would have tempted me would have been multiclassing and hybrid rules for Essentials builds. We saw the feats, and they were a huge letdown, so that certainly wouldn't have done it. We'll see next month about the hybrid rules, I suppose.
