I don't care much for the hyperbole of 'dying', but to say Poser 11 has been slow off the start seems fair enough. I've upgraded, but only to the non-Pro version.

SuperFly is a nice engine, but it's not ready yet. To make things more complicated, the documentation supplied with Poser 11 is very sparse and not informative for people wanting to learn. I assume it works for people already up to speed with Cycles and just looking for Poser-specific implementations. Learning from examples becomes much harder when Poser 11 ships with only the smallest number of SuperFly materials. Blender/Cycles tutorials might seem the obvious alternative, but since SuperFly does not have all the nodes Blender does you inevitably hit a roadblock somewhere. The experts might argue these can be avoided, but the manual sure doesn't tell the uninitiated how.

That the team at Poser decided to hide GPU accelerated rendering on their new engine behind some arbitrary Pro license is baffling. SuperFly is the major change for most amateur users who might not need or understand all the content-creation tools that come with Pro. What we have now seems to be a render engine that can produce excellent results, but isn't a complete implementation of Cycles making learning it difficult, that doesn't ship with anything close to a meaningful collection of basic materials, and that is about as slow as FireFly unless you put down another $400 so the software magically learns how to make use of your Nvidia GPU hardware.

Had Poser 11 been released with a wide variety of materials that could have been applied to existing content I don't doubt we'd have seen a much larger number of SuperFly renders. Just dumping the software on the market and expecting people to dig through obscure forums for screenshots (making Google searches useless) of Poser-specific node setups is such an odd business decision.
