Hello Jack, welcome to the Forum!
I'd say the American print mags are generally fair but often short and incomplete, in their coverage of Pentax DSLR's.
However, the online reviews worldwide are another story entirely;

With a couple of exceptions, they're all in praise of the K-3 and several describe it as the best APS-C DSLR available. Comparable and even superior to, the Canon 70D and the Nikon D7100, at least in several/most areas of performance.
Which must be countered by their product's lack of store on-shelf presence, little advertising and small userbase.
With just a couple camera/lens introductions each year, they can't (and shouldn't) try to compete with C/N's constant upgrading and headline-grabbing.
So, generally, any good publicity helps, but it's still an uphill battle!
