That's rather under-selling it.
Judging by what pictures ? The whole Blizzard Cinematics team is using it to produce absolutely amazing...Blizzard level quality.
I've played with Redshift about year ago and some of my observances:
-It's actually fast GPU renderer. That cannot be said about any other GPU renderer on the market, Redshift really is ahead, massively. But it has drawbacks of course, that speed is either at expense of GI (using general brute force), or quality/precision because you have to use (or rather, have the option to use) Irradiance caching for interiors. I presume some of those IR renders can resemble old Vray renders because it's the same underlying tech.
-It had great PBR shader from second version, and also supported Arnold's AlShader at same time. That's two industry level PBR shaders at same time with all the nice things to boot (correct fresnel, multiple BRDFs like GGX and Oren-Nayar)
-It was the first (and still the only?) GPU renderer capable of out-of-core rendering, cycling the limited GPU's memory buffers. This is massive limitation for big productions.
It's basically GPU speeded up Arnold for the masses. More than well deserving its praise imho :- ).
Now there are renderers running almost purely on hype and strangely religious cargo-culting, but Redshift is not among them.
