I don't know any way of telling how well it is catching on, but if you want to get some idea of how it is selling, check the Amazon sales rank.
When I checked it earlier this week, the C&C PHB had a better (lower numerically) sales rank than: Ars Magica 5e, Decipher's Lord of the Rings, Spycraft, BESM d20, Exalted, Mongoose's Conan, Hackmaster PHB, Hero 5e, Feng Shui, Pendragon, BESM (tri-stat), Jadeclaw, Paranoia XP, Heroquest, d6 Adventure, Ironclaw, d6 Space, HARP, d6 Fantasy, & Savage Worlds.
(It was really sad to me to see how much better BESM d20 was doing than the tri-stat BESM.)
Of course, there's lots of things doing better than it, including: D&D PHB (WotC), Star Wars d20, T20, Mutants & Masterminds, GURPS Basic Set 1 & 2, d20 Modern, & d20 Future.
If you think you'd like something with fewer rules/complexity than d20 D&D, but C&C doesn't float your boat, maybe you should check out TLG's other recent release: Lejendary Adventure Essentials. EGG's latest work, IMHO, fills an interesting spot between class-based systems & skill-based systems.
Plus, unlike the C&C PHB, it includes monsters with only a few more pages overall!
(Oh no, if I haven't before, I really must be sounding like a TLG shill now...maybe I should complain about the C&C 2WF rules...
)
